Stepper motor
Basic function principles of a stepper motor Like most electric motors, a stepper motor consists of a stator (fixed external winding) and a rotor (rotating shaft with magnets). the polarity of the whole coil is reversed in all instances, and not just one half. If the stepper motor … Access Doc
