开关磁阻电机径向电磁力解析建模及有限元分析

在考虑磁饱和与开关磁阻电机实际定转子极弧不等宽的前提下，结合麦克斯韦张量法和磁路法，推导建立一套能直接应用于开关磁阻电机定、转子极弧相等与不相等两种情况下的径向力的通用解析模型。该模型符合实际开关磁阻电机结构及运行特点，为开关磁阻电机结构优化设计、电磁振动和噪声的预测和控制提供了理论参考。以1台样机为例，将解析模型的计算结果与三维有限元分析结果进行了对比，验证了所建解析模型的有效性。

Analytical and FEM modeling of electromagnetic radial force for switched reluctance motor

Based on the magnetic method combining the Maxwell tensor in considering magnetic saturation method,magnetic saturation effect and actual switched reluctance motor stator and rotor under the premise of big width,an analytical model of radial force which can directly apply to switched reluctance motor stator and rotor was set up with extremely unequal and equal arc to two circumstances analytical models of radial force.This model conforms to the actual switched reluctance motor structure and operation characteristics and structure optimization design,electromagnetic vibration and noise prediction and control provides theory basis of switched reluctance motor.With a prototype as an example,results show that the analytical model of the 3D finite element analysis of the results compared to verify the correctness of the analytical model.
