Product Description
Permanent magnet stepper motor, also known as PM stepper motor. The rotor adopts permanent magnet steel. The stator of this stepping motor is processed into claw tooth pole by stamping, and the rotor is made of radial multipole magnetized permanent magnet steel. This kind of motor is cheap.
Principle: the magnetic field generated by the coil current direction and the rotor magnetic field repel each other, so as to make the motor rotate forward / reverse.
