  • What is a stepper motor Principles types and crontollers

    Whereas PM motors are basically 2-phase machines VR motors require at least 3 phases. Most VR stepper motors have 3 or 4 phases although 5-phase VR motors are available. In a VR stepper motor the field moves at a different rate than the rotor. Note that Phase A coil has two south poles and no north poles for a flux return path.
