Kusukela ekuhlaziyweni kwezimo ezimbili ezinembile zokungalayishi nokulayisha, ingakwazingokuyisisekelo kucatshangelwe ukuthi ngaphansi kwesimo somthwalo we-motor, ngenxa yokuthi idonsa umthwalo, izohambisana nomthamo omkhulu, okungukuthi, umthamo wamanje we-motor uzoba mkhulu kunamanje ongenawo umthwalo; kodwa lokhuIsimo asisebenzi kuwo wonke ama-motor, okungukuthi, amanye ama-motor ane-current yomthwalo omkhulu kunomthwalo wawo wamanje.
Kunemisebenzi emibili kagesi yengxenye ye-stator ye-asynchronous motor: eyodwa ukufaka amandla kagesi, kanti enye iwukusungula insimu yamagnetic ejikelezayo yemoto.
Esimweni sokungalayishwa kwemoto, ingxenye yamanje ngokuyinhloko ingumsinga wokuvusa, futhi okwamanje okusebenzayo okuhambisana nokulahlekelwa okungekho umthwalo kuncane kakhulu.Okusho ukuthi, amandla kagesi okufakwayo mancane lapho kungekho-mthwalo, futhi i-stator yamanje isetshenziselwa ukusungula insimu yamagnetic.
Esimeni sokulayisha, amandla engeziwe adinga ukufakwa ukushayela umthwalo. Ngokuvamile, ingxenye yamanje ngokuyinhloko iwumthwalo wamanje, ngakho-ke umthamo wamanje uvame ukuba mkhulu kunowamanje ongalayishiwe, futhi okwamanje ongalayishi kuphela u-1/4 kuya ku-1/2 womthwalo wamanje. phakathi.
Ukuguqulwa kwamandla e-electromechanical ngaphakathi kwemoto kuyinkqubo eyinkimbinkimbi kakhulu. Ukusungulwa kwendawo kazibuthe njengendlela okuwukuphela kwayo yokuguqulwa kwe-electromechanical kuhilela izici ezihlukahlukene, okuholela eqinisweni lokuthi amandla amanje angenamthwalo weminye imiklamo ekhethekile noma izinhlobo zamamotho mkhulu kunomthwalo wamanje.
Ngenjini ye-asynchronous enezigaba ezintathu, ama-windings ezigaba ezintathu asatshalaliswa ngokulinganayo emkhathini, futhi okokufaka kwesigaba sesithathu samanje ku-symmetrical. Kunokuba ube nesimiso esithile. Kodwa-ke, kwamanye amamotho aklanywe ngokukhethekile, njengenjini ejika isigxobo esisodwa eshintsha isivinini esinejubane elithile noma inombolo yezigxobo, ukusabela kokuvuza noma ukuvuza kukhulu kakhulu, kanye nokwehla kwamandla kagesi okuvuza okubangelwa umthwalo. yamanje inkulu, okuholela ezingeni lokugcwala kwesekethe kazibuthe ngaphansi komthwalo. Iphansi kakhulu kunokungalayishi, amandla ashukumisayo omthwalo mancane kakhulu kuneyamanje evusa amadlingozi engalayishiwe, okuholela ekutheni amandla akhona angalayishi abe mkhulu kunomthwalo wamanje.
I-magnetic field ye-single-phase motor iyinsimu yamagnetic elliptical, futhi i-elliptical ihlukile phakathi kokungalayishwa nomthwalo, futhi ngokuvamile inomehluko omkhulu.Ngokuvamile, i-stator ye-asynchronous motor yesigaba esisodwa inamasethi amabili ama-winding ayinhloko kanye ne-axiliary, futhi izimbazo zazo zivame ukuhluka ngo-90 ° emkhathini. I-axiliary winding ixhunywe kugridi yamandla ngokuhambisana nokuvunguza okuyinhloko ngemva kokuba i-capacitor efanelekile ixhunywe ochungechungeni.Ngenxa yomphumela wokuhlukaniswa kwesigaba wezingxenye ezifana nama-capacitor, i-current of the main winding kanye nama-winging ayisizayo ahluka nge-engeli yesigaba ngokuhamba kwesikhathi, namandla kazibuthe wokudlidliza okhiqizwa ukuvunguza okuyinhloko kanye namawindi asizayo ngokulandelanayo angahlanganiswa amandla kazibuthe ajikelezayo, futhi i-current induced in the rotor iyasungulwa. Inkambu kazibuthe iyengelwa, futhi izingxenye ezimbili kazibuthe ziyasebenzisana ukuze zenze i-torque yokudonsa yenjini.Ukuhlaziywa kwetiyori kufakazela ukuthi amandla kazibuthe e-elliptical synthetic ajikelezayo emotho yesigaba esisodwa angahle ahlukaniswe abe amandla kazibuthe amabili ayindilinga ajikelezayo okulandelana okuhle nokunegethivu. Isenzo, ukuze ubukhulu be-torque yokudonsa buthinteke kakhulu.
Lapho ukusatshalaliswa kwendawo kwamawindi amakhulu nayisizayo kanye nomehluko wesigaba sesikhathi sokugeleza kwamanje kokubili kuyi-engeli kagesi engu-90 degrees, i-ellipticity yensimu kazibuthe yokwenziwa incane kakhulu; uma ubukhulu bamandla kazibuthe we-winding main kanye ne-axiliary windings efanayo, icala le-ellipticity encane kunazo zonke ze-synthetic field magnetic liguqulwa libe yindilinga. ukuzungezisa, ingxenye yokulandelana okuyinegethivu inguziro, futhi inkomba yokusebenza nayo ilungile.Ngenxa yokuthi izingxenye zesigaba sokuhlukaniswa njengama-capacitor zifinyelela amazinga ahlukene we-offset yesigaba samanje ngesivinini esihlukile, abukho ubudlelwano obuphelele bokulinganisa phakathi kwamandla amanje ongalayishi kanye nomthwalo wamanje wenjini yesigaba esisodwa. Amanye ama-currents okulayisha makhulu kunama-non-load currents, kanti amanye angalayishi azoba makhulu kunomthwalo wamanje.
