Motoci asynchronous mai mataki ukusu ne abin da muke yawan kira AC motors
Abubuwan da ake buƙata don jujjuyawar injunan asynchronous mai hawa uku shine samun filin maganadisu mai juyawa. Ana amfani da iskar iskar injuna na injinan asynchronous mataki uku don samar da filayen maganadisu masu juyawa. Kamar yadda kowa ya sani, ƙarfin ƙarfin lokaci-zuwa-lokaci tsakanin matakai ya bambanta da digiri 120, kuma kwatancen sararin samaniya na windings uku na stator na injin asynchronous mai hawa uku shima ya bambanta da digiri 120. Ta wannan hanyar, lokacin da iskar stator ta wuce, lokacin da aka kunna wutar lantarki mai matakai uku, na'urar tana haifar da filin maganadisu mai juyawa.
Filin maganadisu mai jujjuyawa yana jujjuya sau ɗaya a sararin samaniya lokacin da na yanzu ya canza sau ɗaya a kowane zagaye. A wasu kalmomi, saurin jujjuyawar filin maganadisu yana aiki tare da canjin halin yanzu. Gudun jujjuyawar filin maganadisu mai juyawa shine kamar haka. n=60f/P Anan, f shine mitar samar da wutar lantarki, P shine adadin nau'i-nau'i na igiya na filin maganadisu, kuma naúrar n shine adadin juyawa a cikin minti daya. Bisa ga wannan dabarar, saurin motar yana da alaƙa da mitar igiyoyin maganadisu da yawan wutar lantarki.
Juyawa na lokaci gudaMotar asynchronous mai hawa ukushine 1, kuma rotor yana cikin siffar sedan. Lokacin da sinusoidal na lokaci-lokaci ɗaya ya wuce ta iskar stator, motar tana haifar da filin maganadisu na AC. Tsanani da alkiblar wannan filin maganadisu suna canzawa cikin lokaci zuwa lokaci, amma saboda an daidaita shi a sararin samaniya, wannan filin maganadisu kuma ana kiransa filin maganadisu mai motsi. Wannan filin maganadisu na mu'amala mai motsi na iya bazuwa zuwa filayen maganadisu guda biyu masu jujjuyawa tare da gudu iri ɗaya da madaidaicin juzu'i. Lokacin da rotor ya tsaya, waɗannan filayen maganadisu guda biyu masu jujjuyawar suna haifar da juzu'i biyu a cikin na'urar, wanda ke da lebur da kuma gaba da gaba, don haka juzu'in yana 0 lokacin da aka yi su, don haka motar ba ta iya juyawa.
Lokacin da aka yi amfani da ƙarfin waje don juyawainduction ac mai hawa ukua cikin takamaiman shugabanci (juyawa ta agogo, da dai sauransu), motsi na yankan filin maganadisu tsakanin filin maganadisu mai jujjuya da filin maganadisu mai jujjuya a cikin agogon agogo ya zama karami. Motsin layukan maganadisu na ƙarfi yanke tsakanin filin maganadisu mai jujjuya da filin maganadisu mai jujjuya agogon agogo baya ya zama mafi girma. Ta wannan hanyar, ma'auni yana rushewa, jimlar wutar lantarki da aka yi ta hanyar rotor ba zai zama sifili ba, kuma na'urar za ta juya ta hanyar motsa jiki.
