1. permanent magnetic motor comprises:

  • Stator has the electromagnetism winding that is used for magnetic pole of the stator;

    Rotor is arranged coaxially with stator, has air gap between stator and rotor;

    A plurality of permanent magnets are arranged on the rotor periphery, make that the magnetic pole of adjacent magnets is asymmetric, weaken the harmonic component of air-gap flux thus, to reduce the unwanted vibration of rotor torque.
