Abstract: The structure and principle of a contra-rotating dual-rotor flux-modulation motor were analyzed based on magnetic gears.Compared with traditional dual-rotor magnetic motors, the torque proportion of the two rotors is an arbitrary value.A control strategy based on model predictive control (MPC) was studied which has advantages of fast dynamic response and small torque ripple. The simulation and experiment results show that the decoupling control between the inner and outer rotors of the dual-rotor flux-modulation motor can be realized. The introduced control method of MPC can achieve faster dynamic response than that of field-oriented control.
