Yakakwirira yakavimbika 86mm stepper
Nekuda kwekufambira mberi kwetekinoroji, kubatanidzwa kuri kutora mota yekudzora musika.Brushless DC motors (BLDC) uye magineti echigarire synchronous motors (PMSM) ehukuru hwakasiyana uye simba density ari kukurumidza kutsiva mota topologies senge brushed AC/DC uye AC induction.
Brushless DC mota / yekusingaperi magineti synchronous mota ine yakafanana chimiro chemuchina, kunze kweiyo stator mhepo.Dzavo stator windings dzinotora maitiro akasiyana ejometri.Iyo stator inogara yakatarisana nemota magineti.Aya mamotor anogona kupa yakakwira torque pakumhanya kwakaderera, saka akakodzera kwazvo servo mota application.
Brushless DC mota uye anogara magineti synchronous motors haadi mabhurashi uye macommutator kutyaira mota, saka iwo anoshanda zvakanyanya uye akavimbika kupfuura mabhurashi mota.
Brushless DC mota uye inogara magineti synchronous mota shandisa software control algorithm pachinzvimbo chebhurashi uye mechanic commutator kutyaira mota kumhanya.
Iyo mechanic chimiro che brushless DC mota uye chisingaperi magineti synchronous mota iri nyore kwazvo.Kune electromagnetic mhepo inotenderera pane isingatenderere stator yemota.Yakagadzirwa ne rotor inogara magineti.Iyo stator inogona kunge iri mukati kana kunze, uye inogara yakatarisana nemagineti.Asi stator inogara iri chikamu chakagadziriswa, nepo rotor inogara inofamba (inotenderera) chikamu.
Brushless DC mota inogona kuve ne1, 2, 3, 4 kana 5 nhanho.Mazita avo uye maalgorithms ekutyaira anogona kunge akasiyana, asi iwo ane mabhururu.
Mamwe brushless DC motors ane masensa, ayo anogona kubatsira kuwana rotor chinzvimbo.Iyo software algorithm inoshandisa masensa aya (Hall sensors kana encoder) kubatsira mota commutation kana mota kutenderera.Aya ma brushless DC motors ane masensa anodiwa kana application ichida kutangwa pasi pemutoro wakakwira.
Kana iyo brushless DC mota isina sensor yekuwana iyo rotor chinzvimbo, iyo yemasvomhu modhi inoshandiswa.Aya masvomhu modhi anomiririra sensorless algorithms.Mune sensorless algorithm, mota ndiyo sensor.
Kuenzaniswa nebhurashi mota, brushless DC mota uye inogara magineti synchronous mota ine zvimwe zvakakosha system zvakanakira.Ivo vanogona kushandisa yemagetsi commutation scheme kutyaira mota, iyo inogona kuvandudza simba resimba ne20% kusvika 30%.
Mazuvano, zvigadzirwa zvakawanda zvinoda kuchinjika mota kumhanya.Aya mamotor anoda pulse wide modulation (PWM) kushandura kumhanya kwemota.Pulse hupamhi modulation inopa kunyatso kudzora kwekumhanya kwemota uye torque, uye inogona kuona kusiyanisa kumhanya.
