摘　　要：针对面贴式和内置式永磁电机的各自特点,提出一种两者混合的永磁电机转子新结构。采用有限元法建立面贴式、内置式及混合拓扑结构的永磁电机模型,计算三种结构电机的静态磁场,比较分析其等位线分布规律、一极距内气隙磁感应强度幅值分布及磁感应强度的云图分布,提出新型结构的永磁电机在气隙磁场分布上更接近正弦的结论,为此电机的设计、运行等提供理论基础。：For each characteristic of surfacemounted permanent magnet motor and builtin permanent magnet motor, this paper presented a new rotor hybrid topologies structure of both the permanent magnet motors. Surface mounted, builtin and hybrid permanent magnet motor topology model were established using the finite element method for to calculate the static magnetic field three structures of the motor. Comparative analysis of their contour distribution of the pole from the amplitude distribution within the air gap flux density and the flux density of the cloud were done. Airgap magnetic field distribution in permanent magnet motor pro- posed new structure is more close to the sine, which is basis on the motor design, operation and so on.
