Ma motors a Brushless DC amagwiritsidwa ntchito kwambiri pazinthu zosiyanasiyana, kuphatikiza zida zam'mafakitale, zida zamankhwala, ndi zamagetsi zogula. Chimodzi mwazinthu zazikulu zama motorswa ndi jakisoni wolumikizana ndi maginito ozungulira, omwe amagwiritsidwa ntchito popereka magwiridwe antchito abwino komanso odalirika.
Wopangidwa kuchokera ku ufa wa NdFeB komanso chomangira chopangidwa ndi polima wapamwamba kwambiri, cholumikizira cholumikizira cholumikizira maginito ndi maginito ochita bwino kwambiri omwe amapereka maginito apadera komanso kukhazikika. Rotor imapangidwa ndi jekeseni yokhala ndi maginito m'malo mwake, zomwe zimapangitsa kuti ikhale yolimba, yophatikizika, komanso yothandiza.
