Chopopera cha brushless cha 24V cha medical dc

Mota yamagetsi ya DC yopanda burashi (mota ya BLDC kapena mota ya BL), yomwe imadziwikanso kuti mota yosinthidwa zamagetsi (mota ya ECM kapena EC) kapena mota ya DC yosinthika, ndi mota yosinthika pogwiritsa ntchito magetsi amagetsi a direct current (DC). Imagwiritsa ntchito chowongolera cha electronic closed loop kuti isinthe mafunde a DC kupita ku ma windings a mota omwe amapanga maginito omwe amazungulira bwino mumlengalenga ndipo rotor yokhazikika ya maginito imatsatira. Chowongolera chimasintha gawo ndi kukula kwa ma pulse a DC current kuti chiwongolere liwiro ndi mphamvu ya mota. Dongosolo lowongolera ili ndi njira ina yosinthira makina osinthira magetsi (maburashi) omwe amagwiritsidwa ntchito m'magalimoto ambiri amagetsi wamba.

Kapangidwe ka makina opanda brushless motor nthawi zambiri kamakhala kofanana ndi makina okhazikika a maginito synchronous motor (PMSM), koma ikhozanso kukhala makina osinthika osafuna kusintha, kapena makina oyambitsa (asynchronous). Angagwiritsenso ntchito maginito a neodymium ndikukhala opitilira (stator yazunguliridwa ndi rotor), ma inrunners (rotor yazunguliridwa ndi stator), kapena axial (rotor ndi stator ndi zathyathyathya komanso zofanana).[1]

Ubwino wa mota yopanda burashi kuposa mota zopukutidwa ndi burashi ndi chiŵerengero champhamvu kwambiri cha kulemera, liwiro lalikulu, kuwongolera liwiro nthawi yomweyo (rpm) ndi torque, kugwira ntchito bwino kwambiri, komanso kusakonza kocheperako. Ma mota opanda burashi amagwiritsidwa ntchito m'malo monga zida zamakompyuta (ma disk drive, ma printers), zida zamagetsi zogwiritsidwa ntchito ndi manja, ndi magalimoto osiyanasiyana kuyambira ndege mpaka magalimoto. Mu makina ochapira amakono, ma mota a DC opanda burashi alola kusintha malamba a rabara ndi ma gearbox ndi kapangidwe koyendetsa mwachindunji.
