Tarihin injinan lantarki ya samo asali ne tun a shekara ta 1820, lokacin da Hans Christian Oster ya gano tasirin maganadisu na wutar lantarki, kuma bayan shekara guda Michael Faraday ya gano jujjuyawar wutar lantarki tare da gina injin DC na farko.Faraday ya gano induction electromagnetic a cikin 1831, amma sai a 1883 Tesla ya ƙirƙira motar induction (asynchronous).A yau, manyan nau'ikan injunan lantarki suna zama iri ɗaya, DC, ƙaddamarwa (asynchronous) da daidaitawa, duk sun dogara ne akan ka'idodin da Alstead, Faraday da Tesla suka haɓaka kuma suka gano su sama da shekaru ɗari da suka wuce.
Tun da aka ƙirƙiro injin induction, ya zama motar da aka fi amfani da ita a yau saboda fa'idar induction motor akan sauran injinan.Babban fa'idar ita ce induction Motors ba sa buƙatar haɗin wutar lantarki tsakanin sassa na tsaye da jujjuyawar motar, don haka, ba sa buƙatar kowane injin injuna (burashi) kuma injina ne na kulawa.Motocin shigar su ma suna da halayen nauyi mai sauƙi, ƙarancin rashin aiki, inganci mai ƙarfi, da ƙarfi mai ƙarfi.A sakamakon haka, sun fi arha, ƙarfi, kuma ba sa kasawa a cikin babban gudu.Bugu da ƙari, motar na iya yin aiki a cikin yanayi mai fashewa ba tare da walƙiya ba.
Idan aka yi la'akari da duk fa'idodin da ke sama, ana ɗaukar induction motors cikakkun masu canza makamashi na lantarki, duk da haka, ana buƙatar makamashin injina a cikin madaidaicin gudu, inda tsarin sarrafa saurin ba ƙaramin abu bane.Hanya daya tilo mai tasiri don samar da canjin saurin stepless shine samar da wutar lantarki mai kashi uku tare da mitar mai canzawa da girma ga injin asynchronous.Gudun na'ura mai juyi ya dogara da saurin filin maganadisu mai jujjuya wanda stator ke bayarwa, don haka ana buƙatar jujjuya mitar.Ana buƙatar ƙarfin wutar lantarki mai canzawa, an rage ƙarfin motsa jiki a ƙananan mitoci, kuma dole ne a iyakance halin yanzu ta hanyar rage ƙarfin wutar lantarki.
Kafin zuwan na'urorin lantarki na lantarki, ana samun iyakance saurin sarrafa induction motors ta hanyar canza iskar stator uku daga layin delta zuwa haɗin tauraro, wanda ya rage ƙarfin wutar lantarki a cikin iska.Motocin induction suma suna da iskar stator sama da uku don ba da damar bambanta adadin nau'ikan sandar sanda.Duk da haka, motar da ke da iska mai yawa ya fi tsada saboda motar tana buƙatar fiye da tashar jiragen ruwa guda uku kuma kawai keɓaɓɓen gudu ne kawai.Za a iya samun wata madadin hanyar sarrafa saurin tare da injin induction na rotor mai rauni, inda aka kawo ƙarshen juyi na juyi akan zoben zamewa.Koyaya, wannan dabarar a fili tana kawar da mafi yawan fa'idodin induction motors, yayin da kuma gabatar da ƙarin asara, wanda zai iya haifar da rashin aiki ta hanyar sanya resistors ko amsawa a jere a cikin iskar stator na injin induction.
A lokacin, hanyoyin da ke sama su ne kawai ake da su don sarrafa saurin induction motors, kuma injinan DC sun riga sun wanzu tare da madaidaicin madaidaicin gudu waɗanda ba wai kawai sun ba da izinin aiki a cikin quadrant huɗu ba, amma kuma sun rufe babban kewayon wutar lantarki.Suna da inganci sosai kuma suna da iko mai dacewa har ma da amsa mai kyau mai ƙarfi, duk da haka, babban hasaransa shine abin da ake buƙata don goge goge.
