| 摘 要： | 为研究尺寸效应对轴向磁化永磁电机性能的影响，用有限元方法对这种双转子电机的磁场进行仿真计算，得出轴向磁化永磁电机转子的气隙磁密波形分布。分析了转子外形尺寸、充磁极数、磁体厚度和气隙长度对气隙磁密的影响。采用一体化多极磁化方法和深刻蚀成型电铸工艺分别制作了直径10mm电机的转子永磁体和硅片上的平面定子线圈。

| Abstract: | In order to research dimensional effect on the performance of axial magnetic PM motor,the finite element method was applied to simulate and calculate the magnet field of this kind of the double-rotor motor,thus,the flux wave in the air gap of the rotor of the axial PM motor was gained.The influence on the flux wave in the air gap by the rotor shape & dimension,poles numbers of magnetizing,thickness of magnets and length of the air gap were analyzed.Finally,the 10mm diameter PM rotor and planar coil on the s... |
