英文摘要：

Refer to the inner rotor motor,a new structure of 12/22 flux switched permanent magnet external rotormotor was designed.The motor inherites the advantages of both the flux switched permanent magnet motor and the external-rotor motor,and has high power density and high torque density.Using the FEA software parametric model was built of the new switched flux motor,and the characteristics of the motor was studied through the finite element analysis method.The main structure parameters of the motor were optimized to reduce the positioning torque and increase the output torque.The best structure dimensions were determined by the simulation analysis,so as to improve the running performance of the motor.The multiphysical fields transient combined simulation model was built with Maxwell and Simplorer.By analyzing,the correctness of the motor design and optimization methods and the rationality of the control strategy were verified.
