摘　　要：轴向磁通开关磁阻电机定、转子齿形在不同圆周半径上极弧角度变化不一致,利用二维解析法分析该类电机会带来较大误差。该文利用准三维解析法对轴向磁通电机展开径向分层计算,确定电机转子关键位置处的磁链特性。在准三维解析法分析的基础上,利用准三维有限元方法对基于不同铁磁材料的模型进行了比较分析。研究结果和样机测试数据表明:基于有取向硅钢材料的轴向磁通开关磁阻电机定、转子磁极轴线对齐位置处的磁链值可以提高15%,准三维解析法的分层计算精度较高,对于电机初期设计而言,该方法的磁链分析误差从工程上认为是可以接受的。According to the different change ratio between the pole arc of the stator tooth and that of rotor tooth at the different circumferential in the axial flux switched reluctance motor(AFSRM),the quasi-three-dimensional(Q-3-D)analytical method is used to study the AFSRM in the different radial delamination,and the accuracy of the Q-3-D analysis is improved to determine the initial electromagnetic design scheme compared with the result of the two dimensional analysis method.On the basis of Q-3-D analytical method,Q-3-D finite element method is employed to optimize the main design parameters with the different electrical steel material.Research results and prototype test data show that,the electromagnetic performance of the AFSRM with the grain oriented electrical steel is superior to the traditional non oriented material motor.Q-3-D analysis method has a high accuracy,for the initial design of the motor,the analysis error is considered acceptable.
