Babban Motar AC
Motar ACwata na'ura ce da ke juyar da makamashin lantarki na alternating current zuwa makamashin injina.Motar AC tana ƙunshe da iskar lantarki ta lantarki ko rarraba iskar stator da ake amfani da ita don samar da filin maganadisu da jujjuyawar armature ko rotor.Ana yin motar ta hanyar amfani da yanayin jujjuya murɗa mai kuzari a cikin filin maganadisu da ƙarfi.Akwai nau'ikan injin AC guda biyu: Motocin AC masu daidaitawa da injin induction.
The stator winding na wani mataki uku AC motor ne m coils uku rabu da 120 digiri daga juna, wanda aka haɗa a cikin alwatika ko tauraro siffar.Lokacin da aka yi amfani da halin yanzu mai hawa uku, ana samar da filin maganadisu a cikin kowace na'ura, kuma ana haɗa filayen maganadisu guda uku don samun filin maganadisu mai juyawa.
Motar ACya ƙunshi stator da rotor, kuma akwai nau'ikan injin AC guda biyu: injin AC na aiki tare da injin induction.Duk nau'ikan injina suna haifar da filin maganadisu mai jujjuyawar ta hanyar wucewa AC halin yanzu cikin iskar stator, amma jujjuyawar iska na injin AC mai daidaitawa yawanci yana buƙatar isar da shi tare da halin yanzu na DC (haɗaɗɗen halin yanzu) ta hanyar exciter, yayin da na'ura mai juyi na induction motor baya buƙatar isar da wutar lantarki. bukatar a ciyar da halin yanzu.
The stator winding na mai hawa AC mai hawa uku na asali coils ne guda uku da aka raba da digiri 120 daga juna kuma an haɗa su a cikin alwatika ko siffar tauraro.Lokacin da aka yi amfani da wutar lantarki mai kashi uku, ana samar da filin maganadisu a cikin kowace nada, kuma ana haɗa filayen guda uku don samun filin juyawa.Lokacin da na yanzu ya cika cikakkiyar girgiza guda ɗaya, filin maganadisu mai juyawa yana juyawa daidai mako guda, saboda haka, juyi juyi a cikin minti ɗaya na filin maganadisu mai jujjuya N=60f.Ma'aunin f shine yawan wutar lantarki.
Ana iya rarraba injinan AC zuwa injina na aiki tare da injinan asynchronous (ko injunan da ba sa daidaitawa) gwargwadon ƙimar jujjuyawar juyi.Gudun rotor na injin da ke aiki tare koyaushe daidai yake da saurin filin maganadisu mai jujjuyawa ba tare da la'akari da nauyi ba, don haka wannan saurin ana kiransa saurin daidaitawa, kuma kamar yadda aka ambata a sama, ana ƙayyade shi ne kawai ta hanyar mitar wutar lantarki.Gudun motar asynchronous ba koyaushe ba ne, amma ya dogara da girman kaya da ƙarfin wutar lantarki.Daga cikin injinan asynchronous mai kashi uku, akwai injunan gyarawa da injinan gyara.Yawancin injinan asynchronous a aikace su ne induction Motors ba tare da mai gyarawa ba (amma a layi daya da jerin na'urori masu gyaran fuska guda uku suna da fa'idodin saurin daidaitacce a cikin kewayo da babban ƙarfin wutar lantarki), kuma saurin sa koyaushe yana ƙasa da saurin daidaitawa. .
Manyan aikace-aikace
Motar ACyana da ingancin aiki mafi girma, kuma babu hayaki, ƙura da wari, ba shi da gurɓata muhalli, da ƙarancin hayaniya.Saboda jerin fa'idodinsa, ana amfani da shi sosai a fannoni daban-daban kamar samar da masana'antu da noma, sufuri, tsaron ƙasa, kayan kasuwanci da na gida, kayan lantarki na likita, da sauransu.
