Hi am using unipolar stepper motor by using 4 NMOS chip each source connected to ground and each drain connected to corresponding coil and gate from Microcontroller .and common connected to 12v .
i dont know the rated current /voltage of this motor , but i measured the coil resistance [common to A pole 2E and A to -A is 4E like in B side also same ] . when i connected to 12v which heating more and not rotaing but vibrating with big sound , and wire got burn , please help me.
