摘　　要：磁悬浮飞轮用永磁无刷直流电机具有大气隙、小长径比的结构特点。采用AN SY S有限元软件对电机进行了三维场建模分析。提出了一种针对该种电机三维场的等效气隙磁通密度计算系数和等效漏磁系数的计算方法。实际电机的实验结果表明,用这一方法计算的电机设计参数具有足够的精度,能够满足工程实际需要。The brushless direct current motor used in magnetic suspending flywheel features a structure of large air and small ratio of length to diameter. To this kind of motor, 3D magnetic field is analyzed and calculated by using Ansys,and the equivalent magnetic flux leakage factor and the equivalent air-gap magnetic flux density calculating factor, which are important for the motor design, are calculated. The validities of the study and calculation are verified by the practical magnetic suspending flywheel motor experiments.
