Kunoma iyiphi injini, inqobo nje uma ukusebenza kwangempela kwenjini kungeqi injini elinganiselwe, injini iphephile uma iqhathaniswa, futhi uma i-current idlula i-current rated, ama-motor windings asengozini yokushiswa.Emaphutha emoto ezigaba ezintathu, ukulahlekelwa kwesigaba kuwuhlobo olujwayelekile lwephutha, kodwa ngokuvela kwamadivayisi okuvikela ukusebenza kwezimoto, izinkinga ezinjalo ziye zagwenywa kangcono.
Kodwa-ke, uma kunenkinga yokulahlekelwa kwesigaba emotweni yezigaba ezintathu, ama-windings azoshiswa njalo ngesikhathi esifushane.Izindlela zokuxhuma ezihlukene zinemithetho ehlukene yokushiswa kwama-windings.Ama-motor windings wendlela yokuxhuma i-delta azoba nenkinga yokulahlekelwa kwesigaba.Uma kwenzeka, isigaba esisodwa sizoshiswa kanti ezinye izigaba ezimbili azishintshile;ngenkathi kumajika axhunywe inkanyezi, ukujika kwezigaba ezimbili kuzoshiswa futhi esinye isigaba sizobe siphelele.
Kumawindi ashile, isizathu esibalulekile ukuthi umsinga imelana nawo udlula owamanje olinganisiwe, kodwa ukuthi inkulu kangakanani le msinga kuyinkinga abasebenzisi abaningi benethiwekhi abakhathazeke ngayo kakhulu.Wonke umuntu uzama ukuyiqonda ngokwesilinganiso ngokusebenzisa amafomula athile okubala.Kukhona futhi ochwepheshe abaningi abenze ukuhlaziywa okukhethekile kulesi sici, kodwa ekubaleni okuhlukene nokuhlaziya, kuhlale kunezici ezithile ezingenakulinganiswa, okuzoholela ekuphambukeni okukhulu kwamanje, okubuye kube yisihloko sempikiswano eqhubekayo.
Lapho i-motor iqala futhi isebenza ngokujwayelekile, i-current phase alternating yamanje ingumthwalo we-symmetrical, futhi imisinga yezigaba ezintathu ilingana ngobukhulu futhi ingaphansi noma ilingana nenani elilinganiselwe.Uma ukunqanyulwa kwesigaba esisodwa kwenzeka, okwamanje imigqa yesigaba esisodwa noma ezimbili izoba ngu-zero, futhi okwamanje imigqa yesigaba esisele izokwanda.Sithatha umthwalo ngesikhathi sokusebenza kukagesi njengomthwalo olinganisiwe, futhi sihlaziya isimo samanje ngekhwalithi kusukela ebudlelwaneni bokusabalalisa bokumelana nama-winging kanye ne-torque ngemva kokuhluleka kwesigaba.
Uma i-motor exhunywe ku-delta isebenza ngokujwayelekile kumanani alinganiselwe, isigaba samanje seqembu ngalinye lama-windings siphindwe izikhathi ezingu-1/1.732 kunamanje olinganiselwe (umugqa wamanje) wenjini.Uma isigaba esisodwa sinqanyuliwe, ama-winding ezigaba ezimbili axhunywe ochungechungeni futhi esinye isigaba sixhunywe ngokuhambisana.Umsinga omazombezombe ophethe i-voltage yomugqa wodwa uzofinyelela izikhathi ezingaphezu kwezingu-2.5 kunamanje olinganisiwe, okuzokwenza ukuthi ukusonga kushiswe ngesikhathi esifushane kakhulu, kanti amanye ama-wiring-izigaba ezimbili mancane futhi ngokuvamile asesimweni esihle.
Ngenjini exhunywe inkanyezi, lapho isigaba sinqanyulwa, amanye ama-winding ezigaba ezimbili axhunywe ochungechungeni ngokunikezwa kwamandla,
Uma umthwalo uhlala ungashintshiwe, i-current yesigaba esinqanyuliwe ingu-zero, kanti i-current yezinye izigaba ezimbili ezijikajikayo zikhuphuka zibe ngaphezu kokuphindwe kabili kwamandla amanje, okubangela ukuthi ama-windings ezigaba ezimbili ashise futhi ashise.
Kodwa-ke, kusukela ekuhlaziyweni kwayo yonke inqubo yokulahlekelwa kwesigaba, izici ezihlukahlukene ezifana nama-windings ahlukene, izimo ezihlukene zekhwalithi ze-windings, nezimo zangempela zomthwalo zizoholela ekushintsheni okuyinkimbinkimbi okwamanje, okungenakubalwa futhi kuhlaziywe kusuka kumafomula alula.Singakwazi kuphela Ukuhlaziya okunzima kwenziwa kwezinye izimo ezilinganiselwe kanye nezindlela ezifanele.
