Permanent magineti synchronous mota inonyanya kuumbwa ne stator, rotor uye zvivakwa zvedzimba. Kufanana neyakajairwa AC motors, iyo stator musimboti chimiro chelaminated kudzikisa kurasikirwa kwesimbi nekuda kweeddy yazvino uye hysteresis mhedzisiro panguva yekushanda kwemota; iwo ma windings anowanzowo matatu-phase symmetrical zvimiro, asi iyo parameter sarudzo yakatosiyana. Iyo rotor chikamu chine mafomu akasiyana, anosanganisira anogara magineti rotor ane kutanga squirrel makeji, uye akavakirwa-mukati kana pamusoro-akaiswa akachena anogara magineti rotor. Iyo rotor core inogona kugadzirwa kuva yakasimba chimiro kana laminated. Iyo rotor yakashongedzerwa nekusingaperi magineti zvinhu, izvo zvinowanzonzi magineti simbi.
Pasi pekushanda kwakajairwa kwechigarire magineti mota, iyo rotor uye stator magineti iri munzvimbo inopindirana, hapana induced ikozvino muchikamu cherotor, hapana rotor copper kurasikirwa, hysteresis, uye eddy ikozvino kurasikirwa, uye hapana chikonzero. kufunga nezve dambudziko rekurasikirwa kwe rotor uye chizvarwa chekupisa. Kazhinji, iyo inogara magineti mota inofambiswa neakakosha frequency converter, uye zvakasikwa ine yakapfava yekutanga basa. Uye zvakare, iyo inogara magineti mota ndeye synchronous mota, ine hunhu hwekugadzirisa iyo simba chinhu cheiyo synchronous mota kuburikidza nesimba reiyo excitation, saka iyo simba chinhu chinogona kugadzirwa kune yakatarwa kukosha.
Kubva pamaonero ekutanga, nekuda kwekuti iyo inogara magineti mota inotangwa neiyo inochinja frequency magetsi kana inotsigira frequency converter, yekutanga maitiro echigarire magineti mota iri nyore kuona; zvakafanana nekutanga kweiyo inosiyana frequency mota, inodzivirira kukanganisa kwekutanga kweyakajairika cage-mhando asynchronous mota.
Muchidimbu, kushanda nesimba uye simba chinhu chekusingaperi magineti motors inogona kusvika yakakwira zvakanyanya, uye chimiro chiri nyore kwazvo. Musika uyu wange uchipisa zvakanyanya mumakore gumi apfuura.
Nekudaro, kutadza kwe demagnetization idambudziko risingadzivisike rekusingaperi magineti mota. Kana iyo yazvino yakakwira zvakanyanya kana tembiricha yakakwira zvakanyanya, tembiricha yemotor windings ichakwira ipapo, iyo yazvino ichawedzera zvakanyanya, uye magineti asingagumi acharasikirwa nemagnetism nekukurumidza. Muchigarire magineti mota control, chidziviriro chepamusoro chakaiswa kudzivirira dambudziko remota stator mhepo ichipiswa, asi kurasikirwa kunokonzeresa kwemagineti uye kuvharika kwemidziyo hazvidzivisike.
Kuenzaniswa nemamwe mota, kushandiswa kwemagineti echigarire mumusika hakuna kufarirwa zvakanyanya. Kune mamwe asingazivikanwe tekinoroji mapofu mapofu kune vese vanogadzira mota nevashandisi, kunyanya kana zvasvika pakufananidza ne frequency converters, izvo zvinowanzo tungamira dhizaini Ukoshi hauenderane zvakanyanya neiyo data yekuyedza uye inofanirwa kuverengerwa kakawanda.
