The rotor of permanent magnet stepper motor is made of permanent magnet steel. The stator of the stepper motor is processed into a claw-shaped tooth pole by stamping method, and the rotor adopts a permanent magnet magnetic steel with radial multi-pole magnetization. The magnetic field generated by the direction of the coil current is mutually exclusive with the rotor magnetic field, so that the motor rotates reversely.

This stepper motor is also known as pm stepper motor, the axial direction of the whole motor stator and rotor is divided into two sections, and the middle is separated by a magnetic separation piece. The two sections are mutually separated by a step angle, and each consists of a stator, a rotor and a ring winding which is sleeved on the stator. The pm stepper motor is mainly used in computer peripheral equipment, photographic systems, optoelectronic combination devices, valve control, nuclear reactors, bank terminals, CNC machine tools, automatic winding machines, electronic watches and medical equipment, etc.
