摘　　要：根据电动汽车对驱动电机性能要求,结合双凸极电机的特点,提出一种外转子结构的双凸极永磁电动机。分别对电机空载、负载以及电枢磁场单独作用3种情况下进行了有限元分析,得出在1个永磁磁链周期内不同转子位置角和不同电枢电流作用下的磁场分布图以及静态参数特性曲线。从场的角度分析和说明了电枢磁场对绕组电感特性的影响,电机的静态参数也为该电机进一步的仿真分析提供了依据。This paper proposes a doubly salient permanent magnet motor with external rotor in the terms of characteristics request of driving motor of electric vehicle and characteristics of doubly salient motor. It makes finite element analysis for no-load motor, full-load motor and armature magnetic field singly acting motor, and it gets distributing map of magnetic field and static characteristics curve as different rotor angle and different armature current in a permanent magnet circle for the motor. It analyzes and explains influences of armature magnetic field on the inductance characteristics of windings. The static parameters of the motor paves the way for furthering simulation analysis of the motor.
