PM stepper motor

The rotor of the permanent magnet stepper motor is made of permanent magnet steel, while the stator features claw-shaped teeth formed by stamping. The rotor uses radially magnetized permanent magnet steel. The magnetic field of the coil current interacts with the rotor's magnetic field to drive rotation.

This motor, also called a PM stepper motor, has a stator and rotor divided by a magnetic separator, with each section comprising a stator, rotor, and ring winding. It's commonly used in applications such as computer peripherals, photographic systems, CNC machines, medical devices, and more.
