20 series PM permanent magnet screw stepper motor

█ Product Introduction

The rotor of the Leili PM stepping motor uses permanent magnetic materials. The PM stepping motor’s continuous operation follows the principle that the same poles repel and different poles attract between the rotor and the stator. It is generally an inner rotor type motor, and the N and S poles are evenly distributed on the outer surface of the cylindrical rotor (The outer surface is toothless). PM stepping motors are usually two-phase, with small torque and volume.
