Motocin Bipolar:
Motocin mu na bipolar gabaɗaya suna da matakai biyu ne kawai, Fase A da Fase B, kuma kowane lokaci yana da wayoyi masu fita guda biyu, waɗanda ke da iska daban. Babu alaka tsakanin matakan biyu. Motocin Bipolar suna da wayoyi 4 masu fita.
Motocin Unipolar:
Motocin mu unipolar gabaɗaya suna da matakai huɗu. Dangane da matakai biyu na injunan bipolar, ana ƙara layukan gama gari guda biyu.
Idan an haɗa wayoyi na gama gari tare, wayoyi masu fita sune wayoyi 5.
Idan ba a haɗa wayoyi na gama gari tare ba, wayoyi masu fita su ne wayoyi 6.
Motar unipolar tana da layukan fita 5 ko 6.
