Abstract：In order to improve the problem of torque dead zone of single-phase hybrid excitation flux switching motor(HEFSM), an asymmetric rotor structure is analyzed as a solution. At first, the structural characteristics are presented. Due to the adoption of asymmetric rotor structure the magnetic field distribution of HEFSM becomes more complex. Based on the simplified circuit model, a simplified modeling method is proposed. It can achieve the description of electromagnetic torque. The results of both finite element analysis of given current and co-simulation prove that the asymmetric rotor structure can effectively improve the problem of torque dead zone of single-phase HEFSM. The experimental test result shows that the simplified model is accuracy and the effect of improving the torque dead zone is obvious.
