About 'ac motor'-What Is the Difference between AC and DC Motors








Electric               cars,               these               are               something               I               remember               reading               about               in               Elementary               school.

Around               the               turn               of               the               millennium               there               were               all               sorts               of               buzzing               about               what               to               expect               in               the               next               century.

Electric               cars               were               definitely               in               the               buzz,               so               were               flying               cars.

Apparently               the               reality               of               electric               cars               is               definitely               closer               and               a               much               more               realistic               concept.

Nissan               plans               to               sell               electric               cars               within               the               next               4               years.

The               subcompact               electric               cars               will               be               powered               by               lithium-ion               batteries               which               were               self-developed               by               the               Nissan               Motor               Company.
               Nissan               is               Japan's               Number               2               automaker               and               they               also               intend               to               develop               and               sell               gas-electric               hybrid               cars               by               the               year               2010,               attempting               to               catch               up               with               competitors               including;               Honda               Motor               Co,               Toyota               Motor               Corp,               and               other               car               companies               with               economically               and               environmentally               friendly               vehicles.
               The               company               is               in               cooperation               with               Renault               SA,               their               French               partner.

Nissan               is               planning               to               speed               up               the               expansion               of               its               line-up               of               diesel               cars               as               well.

Diesel               cars               are               growing               in               the               global               demand,               according               to               the               Nikkei               business               daily.
               Nissan               is               also               expected               to               develop               bioethanol               cars               with               the               help               of               Renault,               which               Nissan               intends               to               provide               with               fuel               cell               and               hybrid               car               technologies.

Nissan               currently               has               two               electric               vehicles               in               production               including;               the               Altra               EV               and               the               Hypermini               as               well               as               a               hybrid               electric,               Japan's               Tino               Hybrid.
               The               Altra               EV               (Electric               Vehicle)               is               a               4-passenger               vehicle               with               a               maximum               speed               of               75               miles.

Its               not               the               swiftest               car               in               the               world,               but               what               it               lacks               in               speed,               it               makes               up               for               in               environmentally               soundness.

The               Altra               EV               uses               lithium-ion               batteries,               the               same               power               source               used               in               notebook               computers               and               video               recorders.
               The               batteries               are               light               and               have               excellent               energy               density               compared               to               lead-acid               or               nickel-metal               hydride               batteries.

The               batteries               also               do               not               lose               capacity               if               they               are               not               completely               discharged               before               recharging.
               The               Hypermini               is               also               powered               by               lithium-ion               batteries.

This               attractive               and               very               mini               vehicle               has               an               aluminum               frame               which               is               lighter               and               more               rigid               than               the               typical               steel               body.

The               Hypermini's               plastic               raw               materials               are               recycled               from               end-of-use               vehicles               using               a               Nissan               developed               process.

The               Hypermini               also               has               special               tyres               that               allow               driving               up               to               50               miles               with               a               flat.

Also,               the               Hypermini               costs               as               little               as               2               cents               per               mile               to               drive!

That's               what               I               call               a               free               ride,               once               the               car               is               paid               for               of               course.
               The               Hypermini               is               expected               to               help               Japan's               current               problem               of               traffic               pollution.

In               Japan,               traffic               data               shows               that               approximately               90%               of               all               passenger               cars               are               driven               less               than               70%               of               the               day.

Also,               82%               of               the               time               a               vehicle               is               occupied               by               only               one               or               two               passengers.

The               waste               of               petrol               gasoline               or               diesel               is               discouraging.
               The               Hypermini               is               an               attempt               to               reduce               and               overcome               this               unnecessary               waste.

The               car               is               designed               specifically               for               short               commutes               and               is               intended               to               maximize               and               conserve               finite               resources.

Nissan's               goal               is               to               transcend               the               traditional               approach               to               an               electric               car               and               give               it               more               of               a               respectable               and               functional               role               in               society.
               The               Hypermini               is               bold               and               smartly               styled.

Proportions               were               reduced               to               save               weight               and               space.

The               car               appears               more               European               than               Japanese.

Its               swooping               lines               and               soft               curves               are               attractive               and               the               horizontal               row               of               lights               on               both               the               front               and               back               ends               give               the               model               a               unique               and               functional               glow.
               Two               versions               will               be               made               available               including               the               Town               Package               and               the               Leisure               series.

The               Leisure               series               will               have               grated               side               windows               and               a               pop-up               rear               hatch.
               Wheels               are               placed               at               the               four               outer               corners               of               the               car               which               give               a               feeling               of               width               and               also               expand               the               stability               of               the               vehicle.

The               vehicle               is               1,000               millimeters               shorter               than               Nissan's               current               smallest               vehicle,               the               Micra.

The               Hyperminis               are               expected               to               use               approximately               the               same               amount               of               space               as               a               Nissan               Sentra               on               the               road.


               The               Hypermini               can               go               at               least               60               miles               an               hour               and               will               be               powered               by               a               neodymium               magnet               synchronous               electric               motor.

The               vehicle               will               also               be               able               to               travel               130               kilometers               on               a               single               charge.
               The               lithium-ion               batteries               will               be               spread               out               across               the               bottom               of               the               car               floor.

The               batters               are               easily               serviceable               by               floor-pan               hatches               and               a               pull-out               mechanism.
               The               Tino               Hybrid               is               also               an               attractive               little               car               with               only               a               limited               number               available               in               Japan.

This               is               also               a               compact               4               seater               with               a               4-cylinder               1.8L               QG               engine.

The               engine               has               about               100               horsepower               and               an               AC               motor               which               produces               an               additional               22               horsepower               respectively.
               The               world               of               electric               cars               is               certainly               getting               closer               and               other               car               companies               are               expected               to               produce               similar               models               depending               on               the               outcome               of               Nissan's               newest               productions.

    About 'electric window repair'-How to Fix Power Window?








    Electric               fireplaces               are               great               additions               to               any               homes;               they               look               great               and               require               very               little               maintenance.

    Electric               fireplaces               work               by               producing               heat               via               electricity               on               metal               coils               while               a               fan               blows               the               warm               air               out               of               the               fireplace;               the               illusion               of               the               fire               comes               from               lighting               effects               on               fake               logs.

    The               artificial               fires               have               become               more               refined,               often               hard               to               tell               the               difference               between               wood               fireplaces               until               you're               close               up.

    Electric               fireplaces               operate               by               just               lifting               a               switch               (like               a               light               switch)               and               the               unit               is               instantly               working.

    This               article               will               take               a               look               at               10               maintenance               tips               for               electric               fireplaces               to               help               the               unit               run               efficiently.

    1.

    Wires               and               electrical               components
                   Although               electric               fireplaces               do               not               require               much               maintenance               the               electrical               wires               need               to               be               in               good               working               condition               without               being               frayed.

    Exposed               electrical               wires               are               a               favorite               for               household               pets;               make               sure               that               you               check               wires               regularly               to               prevent               any               fire               hazard.
                   2.

    Fan
                   The               fan               that               is               built               into               the               electric               fireplace               unit               is               designed               to               spread               the               electrically               produced               heat               throughout               the               room.

    Occasionally               these               fans               can               malfunction               or               break,               therefore               make               sure               they               are               in               proper               working               condition               regularly.
                   3.

    Have               a               professional               look               at               the               fireplace
                   Electrical               fireplaces               are               only               cost               efficient               if               they               are               in               good               working               order;               therefore               have               an               electrician               or               electric               fireplace               technician               take               a               look               at               the               unit               every               so               often               if               you               feel               that               it               is               not               working               up               to               potential.
                   4.

    Cleaning               the               actual               unit
                   For               both               the               glass               window               and               the               surrounding               areas               (except               brass)               you               can               use               a               mild               soap               and               warm               water               mix               for               best               results.
                   5.

    Make               sure               there               is               nothing               blocking               the               heat               vent
                   Electric               fireplaces               heat               up               very               fast               and               if               you               have               any               items               blocking               the               fanned               heat               vent               it               can               cause               damage               to               the               item               or               surrounding               areas.
                   6.

    Cleaning               brass
                   When               cleaning               any               brasses               pieces               on               an               electric               fireplace               you               should               always               use               brass               cleaner,               this               can               be               found               at               almost               any               hardware               store.

    If               you               avoid               using               a               recommended               brass               cleaner               by               the               manufacturer               you               could               end               up               getting               unattractive               scratches.
                   7.

    Light               bulbs               and               artificial               fire               display
                   Every               so               often               you               will               need               to               replace               the               light               bulbs               that               illuminate               the               unit               causing               the               bright               fire               effect.

    Although               the               fireplace               will               work               without               the               light               bulbs               it               is               not               attractive.

    If               the               artificial               fire               display               seems               to               be               malfunctioning               you               should               call               a               repair               service.
                   8.

    Do               you               need               an               electrician               to               install               the               unit?
                   When               bringing               the               electric               fireplace               home               for               the               first               time               it               is               as               simple               as               just               plugging               it               in               and               flipping               a               light               switch.

    There               is               no               need               for               an               electrician               to               install               the               unit.

    What               to               use               to               clean               the               unit
                   As               mentioned               earlier               a               soft               soap               with               warm               water               is               the               best               method,               but               what               do               you               dry               it               with?

    Use               a               soft               cloth               or               rag               to               wipe               and               clean               the               unit,               basically               any               cloth               that               will               not               scratch.
                   10.

    Can               you               place               objects               near               the               unit,               and               can               my               kids               touch               the               unit               without               being               burned?

    Electric               fireplaces               are               actually               cool               to               the               touch               except               for               near               the               heat               vents,               therefore               you               can               place               objects               near               or               on               the               fireplace               and               kids               can               also               touch               it.

    However               you               do               have               to               be               careful               around               the               heat               vents               as               they               can               get               very               warm               (they               should               never               be               blocked).

    About 'pool pumps'-How to Install a Pool Pump








    Usually               people               with               pools               aren't               too               happy               with               the               thought               of               green.

    Green               in               the               pool               equals               slimy,               yicky,               mossy               stuff               that               no               one               wants               to               swim               in.

    But               there's               a               time               when               green               and               your               pool               can               be               friends               -               when               you               heat               your               pool.

    Save               yourself               some               money,               enjoy               your               pool               longer,               and               help               the               environment               with               these               alternatives               for               heating               your               pool.

    Swimming               pools               can               be               enjoyed               for               recreation               and               exercise               and               can               even               be               therapeutic.
                   However,               most               people               require               a               comfortable               temperature               to               enjoy               a               pool.

    Typically               pools               are               heated               by               heat               pumps               that               can               maintain               a               pool               water               temperature               of               80               -90               degrees               regardless               of               the               weather               outside.

    A               heat               pump               uses               electricity               to               operate               and               maintain               these               warm               water               temperatures.

    With               rising               electricity               costs               and               growing               concern               for               greenhouse               gas               emissions,               many               eco-conscious               pool               owners               or               pool               shoppers               are               looking               for               greener               ways               to               heat               their               pools.
                   Are               there               other               options?
                   Yes.

    Two               other               options               include               solar               pool               heaters               and               gas               pool               heaters.
                   Solar               Pool               Heaters
                   Solar               pool               heaters               use               the               sun's               free               heat               and               therefore               do               not               have               an               operating               cost.

    The               pool               pump               circulates               the               water               through               a               heater               that               is               usually               located               on               the               roof.

    The               pumps               timer               is               generally               set               to               operate               during               sunlight               hours.
                   Solar               heaters               are               recommended               for               recreational               pools               for               people               who               are               comfortable               with               a               pool               water               temperature               ranging               from               the               low               to               mid               80's.

    In               consistently               warm               climates,               such               as               in               Florida,               solar               pool               heaters               can               work               year               round.
                   During               inclement               weather,               a               pool               heated               with               a               solar               pool               heater               will               become               to               cool               to               use               but               it               only               takes               a               few               sunny               days               to               raise               the               temperature               of               the               pool               water               back               into               the               comfortable               range.
                   As               with               heat               pumps,               proper               sizing               of               the               solar               heater               compared               to               the               swimming               pool               size               is               critical.

    Solar               panels               usually               have               a               ten               year               warranty               and               will               typically               last               from               ten               to               twenty               years.
                   Gas               Pool               Heaters
                   Gas               pool               heaters               are               another               option               that               can               be               used               to               heat               pools.

    Gas               pool               heaters               are               ideal               for               heating               pools               quickly               or               for               short               periods               of               time,               such               as               heating               a               pool               when               guests               are               arriving               or               for               a               second               home               that               needs               to               be               heated               only               occassionaly.

    While               very               effective,               gas               pool               heaters               are               expensive               to               use.

    Gas               Heaters               use               natural               or               propane               fuel.

    The               gas               is               burned               in               a               combustion               chamber               and               the               heat               is               transferred               to               the               pool               water.

    A               storage               tank               and               natural               gas               hook               up               are               needed               to               use               a               gas               pool               heater               option.
                   Comparing               the               Cost               of               Pool               Heating               Options
                   The               costs               of               pool               heating               options               will               vary               greatly               depending               on               the               size               of               the               pool               and               the               conditions               surrounding               the               pool.

    These               price               comparisons               are               for               typical               15               x               30               foot               pools               and               include               the               units               and               installation.
                   Heat               Pump               $3,2000               installed
                   Solar               Pool               Heater               $2,450               installed
                   Gas               Pool               Heater               $1,500               installed
                   The               cost               of               using               a               heat               pump               to               heat               a               pool               generally               cost               $250               to               $500               in               electricity               annually.

    Solar               heat               panels               have               no               cost               of               operation               beyond               the               electricity               for               the               pool               pump,               which               may               run               $30               to               $75               per               year.
                   As               you               can               see,               gas               pool               heaters               are               the               least               expensive               to               purchase               and               install.

    However,               beyond               installation,               gas               pool               heater               options               are               the               most               expensive               to               operate.

    The               typical               pool               heated               with               propane               will               cost               approximately               $1,000               to               $1,500               per               year               and               about               half               that               price               for               natural               gas.
                   Can               you               Do               It               Yourself?
                   It               is               strongly               recommended               that               a               professional               make               any               gas               and               electric               hook               up.

    However,               a               handy               person               can               otherwise               install               all               three               types               of               pool               heaters.
                   Solar               pool               heaters               generally               take               1               or               2               days               to               install,               compared               to               less               than               a               day               for               heat               pumps,               and               less               than               half               of               day               for               gas               pool               heaters.
                   Does               your               pool               need               a               blanket?
                   Putting               on               a               sweater               or               adding               an               extra               blanket               to               your               bed               can               allow               you               to               lower               your               thermostat               several               degrees,               saving               you               money               and               reducing               greenhouse               gas               emissions.
                   So               the               same               logic               follows               for               a               pool,               right?

    Putting               a               blanket               or               cover               over               a               pool               can               have               create               a               drastic               savings               for               you.

    A               pool               cover               (something               like               a               Thermal               Pool               Cover)               ranges               in               cost               from               $60.00               to               $130.00               for               most               residential               pools.

    Rollers,               which               make               putting               the               pool               cover               on               and               off               more               convenient,               start               at               around               $185.00.
                   A               pool               cover               is               recommended               to               retain               heat,               no               matter               which               method               you               use               to               heat               your               pool.

    Without               a               pool               cover,               the               effectiveness               of               a               solar               heater               is               drastically               reduced               and               operating               costs               of               both               heat               pumps               and               gas               heaters               is               doubled.
                   However               you               choose               to               heat               your               pool,               a               pool               cover               is               an               eco-friendly               accessory.
                   Using               eco-friendly               solar               pool               heaters               is               a               green               and               reasonable               option               for               those               who               live               in               warmer               climates.

    Along               with               a               pool               cover,               and               some               tolerance               for               fluctuation               in               pool               temperature,               using               solar               to               heat               your               pool               can               be               cost               effective               and               reduce               the               carbon               footprint               from               greenhouse               gas               emissions               associated               with               enjoying               a               pool.

    About 'furnace inducer motor'-What Is a Draft Angle







    Go to last comment about ' furnace inducer motor?' Really useful advice... Hi, I totally agree with you... Thank you for sharing this - very insightful... I would like to link this post to mine on drugs... Interesting and well-written Article...



    About 'furnace inducer motor'-What Is a Draft Angle








    Newer               modern               gas               furnaces               no               longer               have               a               pilot               light               that               the               owner               must               light               themselves.

    Modern               gas               furnaces               have               an               electronic               igniter.

    If               your               furnace               is               not               working               the               igniter               could               be               one               of               many               problems               causing               the               failure.

    The               igniter               is               not               too               difficult               to               troubleshoot               and               replace               if               needed.

    If               you               are               not               familiar               with               gas               furnaces               or               are               the               least               bit               unsure               of               your               technical               abilities               it               is               advised               to               call               for               professional               repair.

    In               many               cases               you               can,               however,               determine               the               source               of               your               problem.

    Before               beginning               any               repair               or               diagnosis               you               should               shut               off               the               gas               and               electric               to               the               unit               you               are               working               on               except.....

    Gas               and               electric:
                   Your               furnace               will               not               operate               if               the               gas               or               electric               to               it               has               been               shut               off.

    You               should               verify               that               the               unit               has               not               been               disconnected               for               any               reason               before               making               any               troubleshooting               attempts.

    You               should               also               check               that               the               thermostat               is               operational               and               in               the               on               position               for               heat.

    It               may               sound               silly               but               in               many               cases               the               electric               switch               to               the               furnace               gets               shut               off               by               accident               and               the               homeowner               wonders               why               they               have               no               heat.
                   How               the               igniter               should               work:
                   The               thermostat               "tells"               your               furnace               that               heat               is               needed               and               the               furnace               should               turn               on.
                   The               blower               -               inducer               motor               should               begin               to               turn.
                   The               pressure               switch,               that               senses               negative               air               pressure               from               the               inducer               motor,               should               close.
                   The               inducer               motor               may               run               for               up               to               thirty               seconds               before               gas               flow               starts.
                   The               igniter               should               glow               and               the               flame               sensor               should               sense               the               flame               from               the               igniter.
                   When               the               flame               sensor               senses               the               flame               from               the               igniter,               the               burners               will               come               on               and               the               heating               cycle               will               start.
                   Checking               and               replacing               the               igniter:
                   If               the               igniter               does               not               glow               the               flame               sensor               will               not               allow               the               gas               to               remain               on.

    The               first               quick               and               easy               determination               for               this               is               if               you               need               to               electrically               turn               your               furnace               off               and               then               back               on               continually               to               get               it               to               run.

    In               many               cases               the               blower               motor               will               continue               to               run               without               any               heat               causing               your               home               to               actually               be               colder.
                   At               this               point               in               your               inspection               you               should               have               your               furnace               manual               or               an               on-line               pictorial               source.

    Be               sure               to               shut               off               the               gas               and               electric               now.

    Examine               the               igniter,               identified               by               your               manual,               but               do               not               touch               the               glass               portion               with               your               bare               hands.

    Oil               residue               from               your               hands               can               cause               a               working               igniter               to               become               non-working.

    If               you               see               any               cracks               of               any               size               you               need               a               new               igniter.

    New               igniters               are               relatively               low               in               cost               and               not               exceptionally               difficult               to               replace.

    Even               so               you               may               wish               to               have               professional               repairs               done               but               you               will               know               in               advance               what               to               expect.
                   If               you               do               not               see               any               cracks               in               the               igniter               you               may               very               well               have               a               different               problem.

    Your               furnace               may               not               be               working               due               to               a               bad               control               board,               dirty               or               bad               flame               sensor               or               bad               limit               or               roll               out               switches.
