Permanent magnet stepper motor

Permanent magnet stepper motor ‌is a type of motor whose working principle is based on the interaction between permanent magnets and electromagnetic coils. This motor usually consists of a permanent magnet rotor and several stators, in which a group of permanent magnets are fixed on the permanent magnet rotor, and several electromagnetic coils are distributed on the stator. The constant magnetic field generated by the permanent magnet interacts with the temporary magnetic field generated by the current passing through the stator electromagnetic coil, resulting in the occurrence of a rotating magnetic field.
