Injini ehambisanayo yemagnethi ehlala njaloAma-PMM (ama-PMM) athole ukunakwa kabanzi ezinhlotsheni ezahlukene zokusebenza ngenxa yokusebenza kwawo kahle kakhulu uma kuqhathaniswa nokwejwayelekileimoto yokungenisa engenazinyathelo ezintathus. Esinye sezici ezibalulekile zokusebenza kahle okuthuthukisiwe sisezicini zokusebenza ezihlukile zama-PMM, ikakhulukazi ngaphansi kwezimo zokusebenza ezijwayelekile.
Injini ehambisanayo yemagnethi ehlala njalo yakhiwe yizingxenye ezintathu eziyinhloko: i-stator, i-rotor, kanye ne-housing. Kufana nejwayelekileimoto yokungenisa i-AC yesigaba ezintathus, umongo we-stator wakhiwe njengesakhiwo esinama-laminated ukuze kuncishiswe ukulahleka kwensimbi okubangelwa yimiphumela yamanje ye-eddy kanye ne-hysteresis ngesikhathi sokusebenza kwemoto. Ukugoqa ngokuvamile kuyisakhiwo esilinganayo sezigaba ezintathu, yize ukukhethwa kwamapharamitha kuhluka kakhulu. Ingxenye ye-rotor itholakala ngezindlela ezahlukahlukene, kufaka phakathi ama-rotor angomazibuthe ahlala njalo anamakheji okuqala e-squirrel kanye nama-rotor angomazibuthe ahlala njalo ahlanganisiwe noma afakwe ebusweni. Umongo we-rotor ungakhiqizwa njengesakhiwo esiqinile noma esinama-laminated. I-rotor ifakwe izinto ezikamazibuthe ezihlala njalo, ezivame ukubizwa ngokuthi insimbi kamazibuthe.
Kuma-motor amagnethi ahlala njalo, amasimu e-rotor kanye ne-stator ayavumelaniswa. Lokhu kusebenza okuhambisanayo kusho ukuthi i-rotor ijikeleza ngesivinini esifanayo nensimu yamagnetic ejikelezayo ekhiqizwa yi-stator. Ngenxa yalokho, akukho current ebangelwayo esigabeni se-rotor. Lokhu kungabikho kwamanje ebangelwayo kubalulekile ngoba kuqeda izinhlobo eziningana zokulahlekelwa amandla ezivame ukuba khona kwezinye izinhlobo zama-motor.
Ngaphezu kwalokho, izinto ze-rotor zibhekene nokulahlekelwa yi-hysteresis kanye nokulahleka kwamanje kwe-eddy njengoba zisabela ensimini yamagnetic eshintshayo. Ngokuphambene nalokho, ama-magnet motor ahlala njalo (I-PMMs) zikhombisa ukulahlekelwa okuncane ngenxa yokungabikho kwe-hysteresis kanye nemiphumela yamanje e-eddy. I-rotor yakhiwe omazibuthe abaphakade, abakhiqiza insimu yamagnetic ngaphandle kwesidingo samandla angaphandle, ngaleyo ndlela bagweme ukulahlekelwa nokushisa okuhambisanayo. Ngaphezu kwalokho, ukwehla kokulahlekelwa yi-rotor kwenza ama-PMM asebenze kahle kakhulu, ngokuvamile adlula u-90%. Lokhu kusebenza kahle okuthuthukisiwe kuhumusha ukusetshenziswa kwamandla okuncishisiwe, izindleko zokusebenza eziphansi, kanye nokukhiqizwa kokushisa okuncishisiwe, okungandisa isikhathi sokuphila kwemoto kanye nezingxenye zayo. Ngamafuphi, ukusebenza okuhambisanayo kwamasimu e-rotor kanye ne-stator kumoto yamagnetic engapheli kususa imisinga ebangelwayo kanye nokulahlekelwa okuhambisana nayo, okwenza isebenze kahle kakhulu kunemoto yokungenisa. Lokhu kusebenza kahle akugcini nje ngokuthuthukisa ukusebenza, kodwa futhi kunegalelo ekongiweni kwamandla kanye nokusimama kwezicelo ezahlukahlukene zezimboni.
