Mota inogara ichienderana nemaginetis (PMMs) dzave kutariswa zvakanyanya mukushandiswa kwakasiyana-siyana nekuda kwekushanda kwavo kwakanaka zvichienzaniswa nekwenguva dzose.mota yemhando yepamusoro ine asynchronous induction mota ine zvikamu zvitatuChimwe chezvinhu zvikuru zvinoita kuti mashandiro ave nani chiri muhunhu hwakasiyana hwemaPMM, kunyanya mumamiriro ekushanda akajairika.
Mota inotenderera ine magineti inopindirana zvachose ine zvikamu zvikuru zvitatu: stator, rotor, uye housing. Zvakafanana neyakajairikamota yeinduction yeAC yechikamu chechitatus, musimboti we stator unogadzirwa sechimiro chakaiswa laminated kuderedza kurasikirwa kwesimbi kunokonzerwa ne eddy current uye hysteresis effects panguva yekushanda kwemota. Kutenderedza kunowanzova chimiro chetatu-phase symmetrical, kunyangwe sarudzo yema parameter yakasiyana zvakanyanya. Chikamu che rotor chinowanikwa mumhando dzakasiyana-siyana, kusanganisira ma permanent magnet rotors ane ma starting squirrel cages uye ma pure epermanent magnet rotors akaiswa kana pamusoro. Musimboti we rotor unogona kugadzirwa sechimiro chakasimba kana laminated. Rotor ine zvinhu zve permanent magnet, izvo zvinowanzonzi magnetic steel.
Kune mota yemagineti inogara iripo, minda yerotor nestator inopindirana. Kushanda uku kunoreva kuti rotor inotenderera nekumhanya kwakafanana nesimba remagineti rinotenderera rinogadzirwa nestator. Nekuda kweizvozvo, hapana induced current muchikamu cherotor. Kushaikwa kweinduced current uku kwakakosha nekuti kunobvisa mhando dzakasiyana dzekurasikirwa kwesimba dzinowanzo kuwanikwa mune mamwe marudzi emota.
Uyezve, zvinhu zve rotor zvinogona kukanganiswa ne hysteresis uye eddy current sezvo zvichipindura kusimba remagineti rinoshanduka. Kusiyana neizvi, magineti emagetsi anogara kwenguva refu (PMMs) inoratidza kurasikirwa kushoma nekuda kwekusavapo kwe hysteresis uye eddy current effects. Rotor inoumbwa nemagineti anogara aripo, ayo anogadzira simba remagineti pasina chikonzero chekunze kwemagetsi, nokudaro achidzivisa kurasikirwa nekupisa kunoenderana nazvo. Uyezve, kudzikira kwekurasikirwa kwerotor kunoita kuti maPMM ashande zvakanaka, kazhinji anopfuura 90%. Kubudirira uku kwakawedzerwa kunoreva kudzikira kwekushandiswa kwesimba, kudzikira kwemari yekushandisa, uye kudzikira kwekugadzirwa kwekupisa, izvo zvinogona kuwedzera hupenyu hwemota nezvikamu zvayo. Muchidimbu, kushanda pamwe chete kweminda yerotor ne stator mumota yemagineti inogara iripo kunobvisa mafungu anokonzerwa nekurasikirwa kunoenderana nawo, zvichiita kuti ishande zvakanyanya kupfuura mota ye induction. Kushanda uku hakungobatsiri chete mashandiro, asiwo kunobatsira mukuchengetedza simba uye kugara kwenguva refu mumabasa akasiyana-siyana emaindasitiri.
