Njinga zamoto zamagetsi zimayendetsedwa ndi mabatire, ma mota amagetsi, ndi zowongolera.
1. Battery: Batire ndiye gwero lamphamvu la njinga yamoto yamagetsi, ndipo magwiridwe ake amakhudza mwachindunji mphamvu yagalimoto. Pakadali pano, mabatire a lithiamu-ayoni ndi mtundu wa batire wamba panjinga zamoto zamagetsi chifukwa chakuchulukira mphamvu komanso kuthamanga kwachangu.
2. Njinga: Motor ndiye gawo lalikulu la njinga yamoto yamagetsi, yomwe imayang'anira kusintha mphamvu yamagetsi ya batri kukhala mphamvu yamakina kuti iyendetse galimotoyo patsogolo. Kutengera ndi zosowa zenizeni, njinga zamoto zamagetsi zimatha kugwiritsa ntchito mitundu yosiyanasiyana yama mota, monga ma DC motors, ma AC asynchronous motors, ndi maginito okhazikika a synchronous motors. Maginito osatha a ma synchronous motors, omwe ali ndi mphamvu zambiri komanso amatha kuwongolera bwino, amagwiritsidwa ntchito kwambiri pamakampani oyendetsa njinga zamoto zamagetsi.
3. Wowongolera: Wowongolera ndi "ubongo" wa njinga yamoto yamagetsi. Imayendetsa bwino galimotoyo potengera momwe galimoto ikuyendetsedwera komanso momwe dalaivala amapangira kuti zitsimikizire kuti zikuyenda bwino komanso mokhazikika. Wowongolera amatetezanso batri kuti isachuluke komanso kutulutsa, kukulitsa moyo wake.
