DC brushless motakapangidwe kamangidwe kabwino kwambiri, kuchokera ku kugwiritsidwa ntchito kwake timatha kumva bwino ntchito yake, phindu la kapangidwe kake ndi kosavuta kugwiritsa ntchito, kugwira ntchito mwachangu, titha kuwona momwe chuma chimapindulira ndikugwiritsa ntchito phindu lololera.
Choyamba, yang'anani kapangidwe kake:
1. A, B ndi C ndi magawo atatu a stator windings, omwe amalumikizidwa ndi zida zosinthira mphamvu V1, V2 ndi V3 pamagetsi osinthira magetsi. Rotor yotsatila ya sensa ya malo imayikidwa pa rotor ya motor.VP1, VP2 ndi VP3 zimagawidwa mofanana pa mapeto a brushless dc motor ndi kusiyana kwa madigiri 120. Malinga ndi chipangizo china chamagetsi, amawunikiridwa ndi kuwala kapena ayi kudzera mu ntchito ya chotsekera chozungulira pa shaft yozungulira ya mota.
2, mafunde a stator a A wamba magetsi, magetsi apano ndi gawo lalikulu la maginito opangidwa ndi maginito osatha pa rotor chifukwa cha kuyanjana pakati pa torque yamagetsi ndi kuzungulira kozungulira, malo a chitsulo cha rotor maginito okhala ndi sensa yamalo kukhala ma siginecha amagetsi, ndiyeno kulamulira magetsi lophimba dera, kotero kuti gawo lililonse mapiringidzo a stator adzakhala, nawonso, conduction, stator gawo panopa pamodzi ndi kusintha kwa rotor udindo mu A zina dongosolo commutation.The conduction mayendedwe a dera magetsi lophimba akhoza kukhala kulumikizidwa ndi kuzungulira kozungulira kwa rotor kuti mukwaniritse kusintha kwamakina.
Chifukwa ma motor motor brushless dc adakhazikitsidwa moyenera, ndiye kuti ndiabwino kugwiritsa ntchito, poyendetsa galimoto, kuwonjezera pakumvetsetsa kapangidwe kake, tiyeneranso kuchita ndikupangitsa kuti kusintha kwake kukhale koyenera, ndipo izi ndi kwenikweni anamanga pa maziko a dongosolo wololera.
