摘要将开关磁阻电机定、转子位置互换,定子极上仅有一套可同时产生悬浮力和转矩的绕组,每套绕组独立控制,转子直驱飞轮,省去机械传动装置,得到更适用于飞轮储能的单绕组磁悬浮飞轮电机。精确的数学模型是稳定控制电机的基础,针对麦克斯韦应力法对积分路线的选取较为敏感的问题,运用有限元分析其电磁特性,引入径向力修正系数,推导出单绕组磁悬浮飞轮电机径向力较精确的数学模型。为保证单绕组磁悬浮飞轮电机能在绕组发生故障时正常悬浮,考虑径向力系数随角度的变化的趋势以及不同齿极下径向力系数的差异,提出无β方向约束径向力补偿和有β方向约束径向力补偿方法。结果表明所提出的补偿方法具有可行性和较高的精确性。

Abstract：The position of rotor and stator in switched reluctance motor is exchanged to obtain the single winding bearingless flywheel motor(SWBFM), which is more useful for flywheel energy storage. The suspension force and torque are produced by single windings and the rotor could direct drive the flywheel with less mechanical transmission. The accurate mathematical model of Maxwell stress tensor method obtained by finite element analysis and the correction factor is the basis to control motor stable and depends on the selection of integrating path. Considering the relationship between the angle and the radial force coefficient, and the difference of radial force coefficient with each tooth pole, radial force compensation methods of βdirection constraint and without βdirection constraint are present to ensure the SWBFM stable suspension under the condition of winding fault. The results show that the proposed compensation methods are feasible and have high precision.
