Zvichienzaniswa nemamota akajairika echikamu chetatu asynchronous, mamota anogara aripo ane magineti anowirirana ane mabhenefiti ekuva ne torque yekutanga yakakwira, nguva pfupi yekutanga uye kugona kuwedzeredza, izvo zvinogona kuderedza kugona kwakaiswa kwemota inotyaira yemidziyo zvichienderana nesimba remubato chaiwo, kuchengetedza simba uye kuderedza mari inoshandiswa muzvinhu zvakatarwa panguva imwe chete.
Kana tichienzanisa, kudzora mota yemagetsi ine magineti asingachinjiki kwenguva refu kwakanakira, kumhanya kunongoonekwa chete nefrequency, mashandiro acho akatsetseka uye akavimbika, uye haachinje nekuchinja kwemutoro nevoltage. Tichifunga nezvehunhu hwemagetsi asingachinjiki, kumhanya kwemotokari yemagetsi isingachinjiki kwenguva refu kunoenderana nechaiyo, zvinosarudza kuti mashandiro emagetsi emagetsi akanaka here, uye akakodzera kudzora frequency.
Kubatsira kwemota isingaperi yemagineti inopindiranairi muzvikamu zviviri zviri pasi uye zviviri zviri pamusoro, kureva kurasikirwa kwakaderera uye kukwira kwetembiricha, simba rakawanda uye kushanda zvakanaka, izvo chaizvo zviri kutsvagwa nevanhu kuti mota ishande, izvo zvinosarudzawo mamiriro ekushandiswa kwemota yemagetsi inogara iripo pamusika.
Mamota emagineti anogara aripo ane kurasikirwa kwakaderera uye kukwira kwekupisa kwakaderera
Sezvo simba remagineti remota inochinjika yemagineti inogara iripo richigadzirwa nemagineti anogara aripo, nokudaro zvichidzivirira simba remagineti kuti rigadzire simba remagineti kuburikidza nekurasikirwa kwekuwedzera, kureva kuti, tinoti kurasikirwa kwemhangura; kushanda kwemota, kushanda kwerotor pasina simba remagetsi, zvichideredza zvakanyanya kukwira kwekupisa kwemota, zvichienderana nehuwandu husina kukwana, mumamiriro akafanana emutoro, kukwira kwekupisa kuchadzikira neinenge 20K.
Simba guru uye kushanda zvakanaka kwemota dzinogara dzichienderana nemagineti
Zvichienzaniswa nemamota asina kuenzana, mamota ane magineti asingaenzana ane hunhu hwakanyanya hwekushanda zvakanaka pamitoro yakareruka, ane mhando dzakasiyana dzekushanda zvakanaka, uye anoshanda zvakanaka kupfuura 90% mukati me25% kusvika 120% yemutoro. Kushanda zvakanaka kwemota dzine magineti asingaenzana kunogona kusvika pazvinodiwa zvemuyero wenyika wekushanda zvakanaka kwesimba rekirasi 1, inova imwe yezvakanakira zvikuru mukuchengetedza simba zvichienzaniswa nemamota asina kuenzana.
Mukushanda chaiko, mota hadziwanzo shanda nesimba rakazara kana dzichityaira mitoro. Chikonzero ndechekuti: kune rumwe rutivi, vagadziri vari musarudzo yemota, kazhinji zvichibva pamamiriro ekushanda emutoro kuti vaone simba remota, uye mukana wemamiriro ekushanda emuganho hauwanzoitiki, panguva imwe chete, kudzivirira kupiswa kwemota mumamiriro ekushanda asina kujairika, dhizaini yacho ichave iri kure nesimba remota kuti risiye margin; kune rumwe rutivi, mugadziri wemota kuitira kuve nechokwadi chekuvimbika kwemota, kazhinji zvichienderana nezvinodiwa nemushandisi zvesimba, uye zvakare kusiya margin yesimba. Kune rumwe rutivi, kuitira kuve nechokwadi chekuvimbika kwemota, mugadziri wemota anowanzo siya margin yesimba zvichienderana nesimba rinodiwa nemushandisi. Izvi zvinotungamira mukushanda chaiko kwemota, basa rakawanda riri musimba rakatarwa riri pasi pe70%, kunyanya mafeni ekutyaira kana mitoro yemapombi, mota inowanzo shanda munzvimbo ine mutoro wechiedza. Kune mota isina muganho, kushanda kwayo kwechiedza kwakaderera zvikuru, nepo mota inogara iine magineti synchronous munzvimbo ine mutoro wechiedza, ichiri kukwanisa kuchengetedza kushanda kwakakwirira.
Simba remota rinogara riripo remagineti rinopindirana (permanent magnet synchronous motor power factor) rakakwirira, uye harina chekuita nehuwandu hwematanho emota, simba remota rinokwana 1, saka kana zvichienzaniswa nemota isina kupindirana (asynchronous motor), simba remota diki, uye nekudaro kushandiswa kwemhangura ye stator yemota kudiki, uye kushanda zvakanaka kwacho kwakakwirawo. Simba remota isina kupindirana riri kuramba richidzikira sezvo huwandu hwematanho emota huchiwedzera. Uyezve, nekuda kwesimba rakawanda remota ine magineti isina kupindirana (permanent magnet synchronous motor), simba remota (transformer) rinogona kudzikiswa, uye panguva imwe chete zvirevo zve switchgear netambo zvinotsigira zvinogona kudzikiswa.
