I-Permanent magnet synchronous motor yakhiwa ikakhulukazi i-stator, i-rotor kanye nezingxenye zezindlu. Njengama-motors e-AC ajwayelekile, i-stator core iyisakhiwo se-laminated ukunciphisa ukulahlekelwa kwensimbi ngenxa yemiphumela ye-eddy yamanje kanye ne-hysteresis ngesikhathi sokusebenza kwemoto; ama-windings nawo ajwayele ukuba yizakhiwo ezilinganayo zezigaba ezintathu, kodwa ukukhethwa kwepharamitha kuhluke kakhulu. Ingxenye ye-rotor inamafomu ahlukahlukene, kufaka phakathi ama-rotor kazibuthe ahlala njalo anamakheji ezingwejeje, kanye namarotha kazibuthe ahlanzekile akhelwe ngaphakathi noma abekwe ngaphezulu. I-rotor core ingenziwa ibe yisakhiwo esiqinile noma i-laminated. I rotor ifakwe unomphela uzibuthe impahla, ngokuvamile ebizwa ngokuthi uzibuthe steel.
Ngaphansi kokusebenza okujwayelekile kwemoto kazibuthe unomphela, i-rotor kanye ne-stator magnetic field zisesimweni esivumelanayo, akukho okwamanje okubangelwa ingxenye ye-rotor, akukho ukulahlekelwa kwethusi kwe-rotor, i-hysteresis, nokulahlekelwa kwamanje kwe-eddy, futhi asikho isidingo. ukucabangela inkinga yokulahlekelwa kwe-rotor nokukhiqiza ukushisa. Ngokuvamile, injini kazibuthe unomphela inikwa amandla isiguquli sefrikhwensi esikhethekile, futhi ngokwemvelo inomsebenzi wokuqala othambile. Ngaphezu kwalokho, injini yamagnetic unomphela iyinjini ehambisanayo, enezici zokulungisa isici samandla se-synchronous motor ngamandla okuvusa, ngakho-ke isici samandla singaklanywa ngenani elicacisiwe.
Ngokombono wokuqala, ngenxa yokuthi injini yamagnetic unomphela iqalwa yi-variable frequency power supply noma isiguquli esisekela imvamisa, inqubo yokuqala yemoto kazibuthe unomphela kulula ukuyibona; efana nokuqala kwe-variable frequency motor, igwema ukukhubazeka kokuqala kwe-cage-type asynchronous motor evamile.
Ngamafuphi, ukusebenza kahle kanye namandla factor of unomphela uzibuthe motors ingafinyelela phezulu kakhulu, futhi isakhiwo silula kakhulu. Imakethe ibishisa kakhulu eminyakeni eyishumi edlule.
Kodwa-ke, ukwehluleka kwe-demagnetization kuyinkinga engenakugwenywa yamamotho kazibuthe unomphela. Uma i-current iphezulu kakhulu noma izinga lokushisa liphezulu kakhulu, izinga lokushisa le-motor windings lizokhuphuka ngokushesha, lamanje lizokhula kakhulu, futhi ama-magnets ahlala njalo azolahlekelwa amandla akho ngokushesha. Esilawulweni semoto kazibuthe unomphela, idivayisi yokuvikela i-overcurrent isethelwe ukugwema inkinga yokushiswa kwamajika e-motor stator, kodwa ukulahlekelwa okuwumphumela wokusebenza kazibuthe nokuvalwa kwemishini akunakugwenywa.
Uma kuqhathaniswa namanye amamotho, ukusetshenziswa kwamamotho kazibuthe ahlala njalo emakethe akudumile kakhulu. Kukhona ezinye izindawo ezingaziwa ezingaboni zobuchwepheshe kubo bobabili abakhiqizi bezimoto nabasebenzisi, ikakhulukazi uma kuziwa ekufaniseni iziguquli zefrikhwensi, okuvame ukuholela ekwakhiweni Inani alihambisani kakhulu nedatha yokuhlola futhi kufanele iqinisekiswe ngokuphindaphindiwe.
