Abstract: In this paper, a multi-objective optimization design method for permanent magnet brushless motor (PMBM) used in EV based on genetic algorithm (GA) and response surface method (RSM) was proposed. Through this method, the design of PMBM for EV can be more convenient and effective, which has a excellent significance to the development of EV. Firstly, the influence of Vshaped magnet rotor structure and its parameter on the performance of PMBM was investigated. Then the procedures to design Vshaped magnet rotor structure of a PMBM were presented, which consist of how to determine the design parameters, objective function, how to construct and solve the RSM function, and how to carry out the optimal design by GA. Finally, the optimal design result was acquired, whose accuracy can be verified by FEM.
