Mota isina mabhurashi yeDcMaumbirwo ayo akaenzana, kumhanya kwayo kwakasimba, saka kazhinji, kazhinji kacho, kudzorwa kwekumhanya kwakanyanya. Nekuti mota ine mashandisirwo akasiyana-siyana uye inogona kushandiswa nemichina yakawanda, zvakakosha kugadzirisa kumhanya kwayo zvichienderana nenguva dzakasiyana. Asi nzira yekudzora nekudzora kumhanya kwemota yeDC isina brushless inoda kuti munhu wese adzidze, kuti ikurumidze kushandiswa:
1. Nekudzora kurongeka kwesimba re coil, coil inopikisana inokamurwa kuita boka uye simba remagetsi rinowedzerwa simba kuti rigadzire simba remagineti munzira imwe chete.
2. Huwandu hwematanda emota yeDC isina brushless hutatu, saka peya imwe neimwe ye "matanda emagineti" inogona kufambiswa nenzira yakati kuti iwane mhedzisiro yekutenderera kwesimba remagineti. Pasi pekushanda kwesimba remagineti, rotor yemagineti inogara iri pakati inogara iine tsika yekuchengetedza simba remagineti riri munzira imwe chete uye ichatenderera nesimba remagineti rinotenderera.
H1H2H3 ma sensor matatu eHall akaiswa mugedhi remhepo re excitation coil, iro rinoshandiswa sechinhu chekuona simba remagineti. Voltage inogona kuchinjwa zvichienderana negwara resimba remagineti, uye chinobuda chiratidzo chedhijitari.
3. Stator coil inowedzerwa simba zvichienderana nekutevera, uye rotor magnetic field ne stator magnetic field zvinofanira kunge zvine Angle. Hapana chikonzero chekutonga kana brushless dc motor ichangotanga, ingoda kuita murairo unotevera zvichienderana nemamiriro ekushanda akatumirwa neHall sensor.
Murairo wayo ndewokutumira mapeya matatu e coil pairi nepairi, ma switch aya anowanikwa kuburikidza ne transistor.
Kutenderera kweBLDC yechikamu chetatu kunogona kuitwa nekupa simba kana kucheka mapeya matatu ematransistors nenzira yakatarwa.
4. Sezvo rotor ichitenderera, simba rinokonzerwa ne coil yega yega rinoenda kubva pakakwirira kusvika pa zero uye rinodzoka zvakare. Nekuti kana coil yawedzerwa simba kune rimwe divi, simba re reverse electromotive richavhara reverse voltage, saka chikamu che trapezoidal wave chichaonekwa. Voltage yakanaka neyakaipa yechikamu che trapezoidal che zero yakatarisana, saka mamiriro ekushanda kwemota stator anogona kutsanangurwa nekuona voltage yakanaka neyakaipa mushure me voltage comparator.
Sezvo zero point iri pakati petrapezoid, kutenderera kweBLDC kunogona kudzorwa mushure mekunge chiratidzo chekudzora chenguva inoenderana chabuda mushure mekunonoka kwe30°. Iyi nzira yekudzora haidi Hall sensor, uye waya nhatu dzinogona kutyairaBLDCKana waveform yacho yakanaka, ma coil voltage curves matatu anogona kuwanikwa nekubatanidza voltage zvakananga. Saka mota ye brushless dc inogona kudzorwa.
5. Sarudza kwaunotanga, tanga wapa simba coil yepasi munzira iyoyo, tanga wapa simba rotor kuenda kunzvimbo yekutanga munguva pfupi, wobva wapa simba mota zvichienderana nezviito zvinotevera.
Kuti tivandudze mashandiro emota yebrushless dc, tinofanira kudzidza kuti zvichienderana nenzvimbo dzakasiyana dzekushandisa, maitiro akasiyana ekudzora nekumhanya, kuvandudza mashandiro emota, nzira yekudzora nekumhanya inogona kushandiswa kugadzirisa kumhanya.
