Kuenzaniswa neDC mota uye asynchronous mota, akakosha tekinoroji maitiro eBrushless DC mota ndeaya:

1.Maitiro ekushanda kweDC motokari anowanikwa nemagetsi ekutonga. Iine zviri nani controllability uye yakafara kumhanya siyana.

2.Rotor chinzvimbo mhinduro ruzivo uye electronic multiphase inverter mutyairi zvinodiwa.

3.Essentially, AC motor inogona kushanda nekumhanya kukuru pasina spark uye abrasion yebrashi uye commutator. Iine kuvimbika kwepamusoro, hupenyu hurefu hwekushanda uye hapana chikonzero chekugadzirisa.

4.Brushless DC motokari ine simba guru, hapana kurasikirwa kwerotor uye kupisa, uye kushanda kwepamusoro: kana ichienzaniswa nedata, kushanda kwe 7.5 kW asynchronous motor i86.4%, uye kushanda kwesimba rakafanana brushless DC motokari inogona kusvika 92.4%. .

5.Panofanira kunge paine zvikamu zvekutonga zvemagetsi, mutengo wakazara wakakwira kupfuura mota yeDC.

Kune anonyanya marudzi maviri emotor anoshandiswa muAC system: induction mota uye inogara magineti synchronous mota. Permanent magineti synchronous mota inogona kukamurwa kuita sinusoidal kumashure EMF inogara magineti synchronous mota (PMSM) uye square wave kumashure EMF brushless DC mota (BLDCM) zvinoenderana neyakasiyana yekushanda musimboti. Saka kuti yavo yekutyaira ikozvino uye control mode zvakasiyana.

Iyo yekumashure EMF ye sinusoidal inogara magineti synchronous mota is sinusoidal. Kuti mota ibudise torque yakatsetseka, yazvino inoyerera kuburikidza nemotor winding inofanira kunge iri sinusoidal. Naizvozvo, iyo inoenderera rotor chinzvimbo chiratidzo inofanirwa kuzivikanwa, uye inverter inogona kupa sinusoidal voltage kana ikozvino kune mota. Naizvozvo, PMSM inoda kutora yakakwira voltage kana yazvino. Kugadziriswa kweiyo chinzvimbo encoder kana kugadzirisa zvakare kwakaoma.

BLDCM haidi yakakwirira-resolution chinzvimbo sensor, chishandiso chemhinduro chiri nyore, uye iyo algorithm yekutonga iri nyore. Pamusoro pezvo, iyo mhepo gap remagineti yeBLDCM trapezoidal wave inoshanda zvakanyanya kupfuura iyo yePMSM sinusoidal wave, uye kuwanda kwesimba kweBLDCM kwakakwira kupfuura iyo yePMSM. Naizvozvo, iko kushandiswa uye kutsvagisa kwechigarire magineti brushless DC mota yakawana kutariswa kwakawanda.
