| 摘 要： | 采用电磁场的数值计算方法,对比分析了常规磁体结构和HALBACH磁体结构的外转子无定子铁心永磁无刷直流电机,重点分析了磁体厚度变化对两种磁体结构电机气隙磁通密度、磁通及转子轭部磁通的影响,认为HALBACH磁体结构特别适于外转子高速飞轮用无铁心电机.提出HALBACH磁体结构电机的场路结合设计计算方法,并通过一25Nms角动量(30000r/min额定转速)的高速外转子飞轮用无铁心永磁无刷直流电动机进行了试验验证.

| Abstract: | Coreless permanent magnet brushless DC machines (BDCM) with Halbach magnet array and normal one are analyzed comparatively, laying emphasis on the variation of their air-gap field density distribution and rotor yoke flux with the magnet thickness. The field-circuit coupling design of coreless BDCM with Halbach array is presented. The prototype is designed and fabricated to verify the theoretical analysis and satisfy the performance demand of satellite attitude control and energy storage flywheel with angular moment of 25Nms at the speed of 30000rpm. |
