Abstract：With the wide application of electric energy, it can be effectively used in the automobile, and thus effectively improve the current situation of oil shortage. The emergence of electric vehicles can effectively improve the current energy shortage problem, which is a core component of the motor drive system of electric vehicle, its performance has very important influence on the overall quality of electric vehicles, electric vehicles can decide the popularization and application in large area. Therefore, the design of permanent magnet synchronous motor with excellent performance is of great practical significance for improving the overall performance of electric vehicles. The parameters of permanent magnet motor requirements were analyzed and studied on the electric car, on this basis, discussed the main dimensions of permanent magnet motor selection, selection, rotor structure of permanent magnet synchronous motor pole permanent magnet motor, permanent magnet motor slot number selection, permanent magnetic air gap length the motor rotor and the selection of weight loss hole analysis, can improve the design quality of permanent magnet synchronous motor of electric vehicle, has a certain reference for technical personnel engaged in related work.
