摘　　要：提出了一种新型结构的轮毂外转子双凸极永磁电动机(DSPM电动机),并以5 kW电动机为例给出了其基本尺寸方案。基于VC++开发的有限元程序对电机空载、负载时的磁场和气隙磁密分布进行了深入的分析计算。分析了永磁体磁场和电枢磁场之间的相互耦合作用对气隙磁密的影响,所得结果为该电动机的设计、性能分析以及运行控制提供了依据。This paper proposes a novel structural doubly salient permanent magnet wheel-hub motor with external rotor and appoints a base sizing scheme about 5 kW sample motor. It analyzes the magnetic field and gap-flux density based on VC ＋＋ finite element programs thinking of no-loading, loading about the motor. It analyzes the influence of air-gap-flux between permanent magnet field and armature field on the characteristics of inducts of the motor, the result supplies references for the motor＇s design, performing analysis and operating control.
