The stator is the core stationary component of permanent magnet motors, assembled with laminated silicon steel sheets and winding coils. When alternating current passes through stator windings, a controllable rotating alternating magnetic field is generated. This magnetic field couples magnetically with permanent magnets (NdFeB, ferrite arc magnets or ring magnets) mounted on the rotor, driving continuous rotor rotation via magnetic attraction and repulsion between magnetic poles to realize the conversion from electrical energy to mechanical energy. Depending on motor construction, some outer-rotor permanent magnet motors embed permanent magnets inside the stator bore while arranging coils on the rotor side, delivering power through magnetic mutual inductance. It serves as an essential foundational part for new-energy motors, servo motors and miniature drive equipment.
