Zvichienzaniswa nemota yeDC uye mota isingaperi, hunhu hukuru hwehunyanzvi hwemota yeBrushless DC ndeiyi:

1. Hunhu hwekushanda kwemota yeDC hunowanikwa nekudzora kwemagetsi. Ine kugona kudzorwa kuri nani uye kumhanya kwakafara.

2. Ruzivo rwemhinduro yenzvimbo yerotor uye dhiraivha yemagetsi yemagetsi ine zvikamu zvakawanda zvinodiwa.

3. Chaizvoizvo, mota yeAC inogona kushanda nekumhanya kwakanyanya isina spark uye kukweshwa kwebhurashi ne commutator. Yakavimbika zvakanyanya, inoshanda kwenguva refu uye haidi kugadziriswa.

4. Mota yeDC isina brush ine simba rakawanda, haina kurasikirwa nerotor nekupisa, uye inoshanda zvakanyanya: kana tichienzanisa nedata, kushanda zvakanaka kwemota ye7.5 kW isina brush i86.4%, uye kushanda zvakanaka kwemota yeDC isina brush kunogona kusvika 92.4%.

5. Panofanira kunge paine zvikamu zvekudzora zvemagetsi, mutengo wese wakakwira kupfuura mota yeDC.

Kune mhando mbiri dzemota dzinoshandiswa muAC system: induction motor uye permanent magnet synchronous motor. Permanent magnet synchronous motor inogona kukamurwa kuita sinusoidal back EMF permanent magnet synchronous motor (PMSM) uye square wave back EMF brushless DC motor (BLDCM) zvichienderana nepfungwa dzakasiyana dzekushanda. Saka nzira yavo yekutyaira uye yekudzora yakasiyana.

EMF yekumashure yemota ye sinusoidal permanent magnet synchronous i sinusoidal. Kuti mota ibudise torque yakatsetseka, magetsi anoyerera nepamota anofanira kunge ari sinusoidal. Saka, chiratidzo che rotor position chinofanira kuzivikanwa, uye inverter inogona kupa sinusoidal voltage kana current kumota. Saka, PMSM inofanira kushandisa high voltage kana current. Resolution ye position encoder kana resolver yakaomawo zvikuru.

BLDM haidi sensor yenzvimbo ine resolution yepamusoro, mudziyo wemhinduro uri nyore, uye algorithm yekudzora iri nyore. Pamusoro pezvo, simba remagineti reBLDCM trapezoidal wave rinoshanda zvakanyanya kupfuura rePMSM sinusoidal wave, uye simba reBLDCM rakakwirira kupfuura rePMSM. Nokudaro, kushandiswa nekutsvagurudzwa kwemota yeDC isina magineti inogara kwenguva refu kwave kutariswa zvakanyanya.
