Impeta imeze nk'impeta ihoraho ihamye muriMoteri ya DC, kandi ikigezweho inyura muri coil kuri rotor kugirango itange imbaraga za ampere. Iyo coil kuri rotor ihwanye numurima wa rukuruzi, icyerekezo cyumurima wa magneti kizahinduka niba gikomeje kuzunguruka. Kubwibyo, guswera kumpera ya rotor bihindurwa hamwe namasahani ahinduranya ubundi buryo, kugirango icyerekezo kigezweho kuri coil nacyo gihinduke, kandi icyerekezo cyingufu za Lorentz zabyaye ntizihinduka, moteri rero irashobora gukomeza kuzunguruka mubyerekezo kimwe.
Ihame ry'akazi ryaAmashanyarazi ya DCni uguhinduranya imbaraga za electromotive imbaraga zatewe muri coil armature imbaraga za DC ya electromotive DC iyo ikuwe kumpera ya brush na komatori n'ingaruka zo kugabanuka kwa brush.
Icyerekezo cyingufu zamashanyarazi zashizweho zigenwa ukurikije itegeko ryiburyo (umurongo wumurongo wa magnetiki werekeza kumikindo, igikumwe werekeza icyerekezo cyerekezo cyumuyoboro, naho izindi ntoki enye zerekana icyerekezo cyingufu zamashanyarazi ziyobowe numuyobora).
Icyerekezo cyingufu kumuyobora kigenwa nubutegetsi bwibumoso. Izi mbaraga za electromagnetic zikora urumuri rukora kuri armature, rwitwa electromagnetic torque mumashini izunguruka. Icyerekezo cya torque nicyerekezo cyamasaha, mugushaka gukora armature kuzenguruka isaha. Niba uyu muriro wa electromagnetique ushobora kunesha urumuri rwo guhangana kuri armature (nka torque yo kurwanya iterwa no guterana amagambo hamwe nubundi buryo bwo kwikorera imitwaro), armature irashobora kuzunguruka mucyerekezo cyamasaha.
