M'galimoto, mayendedwe a mpira omwe amagwiritsidwa ntchito mobwerezabwereza ndi mayendedwe a mpira, omwe amatchedwanso mayendedwe a mpira. Mipira imakhala ndi zigawo zinayi zofunika: zogudubuza, mphete zamkati, mphete zakunja ndi makola.

Sizifanana ndi pamene chitsulo chikupukuta ndi kuyendetsa magetsi kuchitsulo; Maburashi a carbon satero chifukwa mpweya ndi zitsulo ndi zinthu ziwiri zosiyana.

Ma motor swing subassembly ndi gawo lofunikira la mota ndipo nthawi zambiri amakhala ndi maburashi angapo ndi zonyamula maburashi. Zidazi zimagwira ntchito yofunika kwambiri pama motors amagetsi, makamaka mu ma DC motors ndi ma brushed DC motors.

Mudzapeza kuti mukagula chida champhamvu, zinthu zina zimatumiza zida ziwiri zazing'ono m'bokosi. Anthu ena amadziwa kuti ndi burashi wa carbon, ndipo anthu ena sadziwa chomwe amatchedwa kapena kugwiritsa ntchito.

Pepala lotsekera magetsi ndi chinthu chapadera chotchingira chomwe chimagwiritsidwa ntchito popereka chitetezo chamagetsi pazida zamagetsi ndi mabwalo.
