Ukusetshenziswa kwezimoto zegiya kuya ngokuqhubekayo, kukhona uhlobo lwemoto ye-AC encane enemoto ye-DC, eyaziwa nangokuthi i-gaared motor, i-AC emoto e-aared isemoto ejwayelekile ye-DC ngokuyisisekelo, kanye nezinsiza ezisekelayo zokunciphisa amagiya zakhiwe. Umphumela wokushintshana kwemoto yamanje owenziwe ukuletha isilinganiso sejubane esiphansi ukuthola iphimbo elikhudlwana. Ngokwemvelo, kubalulekile futhi ukubona ukuthi izilinganiso ezahlukahlukene ze-gearbox ziyakwazi ukukhiqiza izilinganiso zejubane ezahlukahlukene nama-torque, futhi ngakho-ke isilinganiso sokusebenza sezimoto ze-DC kubuchwepheshe be-automation kuthuthukiswe kakhulu ngenxa yejubane kanye ne-torque okwandayo kwezici ze- ibhokisi le-gear.
