Nekuda kwehunhu hwayo hwakanaka hwemuviri, yakanakisa makemikari zvimiro uye yakanaka maitiro maitiro,magineti zvinhuanoshandiswa zvakanyanya mumotokari chaiyo zvikamu, izvo zvinovandudza zvakanyanya kushanda kwezvikamu zvemotokari. Magnetic zvinhu ndiyo yakakosha zvinhu zvekutyaira mota dzemagetsi matsva. Electrification yave nzira yekusimudzira yeindasitiri yemotokari yepasi rose, uye musika wemagineti une nzvimbo yakakura. Pamusoro pezvo, China ine matura makuru epasirese zviwanikwa pasirese. China ine matura makuru ezviwanikwa zvepasi zvisingawanzo, goho rakakura uye mutengo uye zviwanikwa zvakanakira. Nekuvandudzwa kweindasitiri yemotokari yemagetsi yeChina, iyo yepamusoro-yekupedzisira mota yemagineti uye kusvika kwenzvimbo dzinodiwa inove nzvimbo nyowani yekukura yeindasitiri mune ramangwana.
Muchikamu chepasi chekushandisa kugoverwa kwezvinhu zvemagineti, kushandiswa kweChina kunosvika makumi mashanu muzana. Muchimiro chepasi rose chinodiwa chepamusoro-inoshanda magineti zvinhu, mota account ye52%.
Iyo mota yekutyaira ndechimwe chezvikamu zvitatu zvakakosha zvemotokari nyowani dzesimba. Iyo magineti zvinhu ndiyo huru mbishi zvinhu zve stator uye rotor yemotokari mota. Zvinoenderana nedatha yeBazi reindasitiri uye ruzivo rwehunyanzvi hweChina, pakazosvika Zvita 2019, huwandu hwakaiswa hwemotokari dzemumba muChina hwakanga hwasvika miriyoni 1.24, idzo dzisingaperi magineti synchronous motors dzakaita 99% yemugove wemusika. Permanent magineti synchronous mota inonyanya kuumbwa ne stator, rotor uye mhepo, chivharo chekupedzisira uye zvimwe zvimiro zvemuchina. Hunhu uye kuita kwemagineti zvinhu zvinotarisisa zvakananga zviratidzo senge simba rekuita uye kugadzikana kwechigarire magineti drive mota.
Zvemotokari zvemagineti zvinoshandiswa kutyaira mota dzemagetsi matsva. Iyo mota yekutyaira yemotokari nyowani dzesimba muchina unofamba wemagetsi unoshanda pamusimboti we electromagnetic induction. Inoshandiswa kushandura simba remagetsi kumagetsi emagetsi uye kutora simba remagetsi kubva pamagetsi emagetsi panguva yekushanda. Output mechanical simba kune mechanical system. Yechigarire magineti inodzokera kumashure mota inonyanya kuumbwa ne stator, rotor uye mhepo, chivharo chekupedzisira uye zvimwe zvimiro zvemuchina. Pakati pavo, kunaka uye kuita kwe stator uye rotor cores kunotarisisa kukosha kwezviratidziro zvakakosha senge simba rekuita uye kugadzikana kwemota yekutyaira, inoverengera 19% uye 11% yehuwandu hwehuwandu hwechigarire magineti synchronous mota zvichiteerana. Magnetic zvinhu zvinonyanya kushandiswa mumotokari mota rotor. Kubva kudivi rezvinhu, magineti uye silicon simbi mashiti ndizvo zvakakosha zvinhu zvinotaridza kukosha kwechigarire magineti synchronous mota, accounting ye30% uye 20% yemutengo wakazara zvichiteerana.
Parizvino, mhando dzemadhiraivha ekutyaira anoshandiswa mumotokari dzesimba nyowani dzinonyanya AC asynchronous motors uye inogara magineti synchronous motors. Inoratidza kuwedzera kwemaitiro gore negore. Sesimba sosi yemotokari nyowani dzesimba, inogara magineti synchronous mota (PMSM) ine hunhu hwehurefu hwesimba, kushanda kwakavimbika uye kunogadziriswa kumhanya kuita, zvichienzaniswa nemamwe marudzi emotor. Inogona kupa simba rakakura kubuda pasi pehuremu humwechete uye vhoriyamu, uye imhando yemota yakanakira mota nyowani dzesimba. Pakati pavo, Japan neSouth Korea vanotora chisingaperi magineti synchronous muchina, uye Europe inotora AC asynchronous muchina. Iyo inogara magineti synchronous mota (PMSM) yave inonyanya kushandiswa kushandiswa muchina mumotokari nyowani dzeChina nekuda kwesimba rayo guru, simba rakaderera, diki uye huremu.
