[Abstract]:A new type of stator permanent magnet double-rotor motor applied to the drive system of hybrid electric vehicle is proposed, which combines the concept of double-rotor motor with permanent magnet flux switching motor to obtain high torque density, low torque ripple and high power density. To meet the needs of the hybrid power system for small lightweight and smooth operation. In this paper, the topology of a new stator permanent magnet flux-switched double-rotor motor and the working principle of hybrid drive system are introduced. The design method of internal and external motor and the dimension optimization based on minimum torque ripple are analyzed in detail. The electromagnetic performance of the motor is simulated by finite element method. The simulation results show the rationality of the motor design, the validity of the motor design is verified by the measured data of the principle prototype, and the fast response performance of the internal and external motor is shown. It is shown that the double rotor motor with this structure can effectively increase the torque density. The torque ripple can be reduced and the power requirement of HEV can be satisfied by reasonable design.
