采用矢量位半解析法分析了分数槽电机的永磁气隙磁场和定位转矩.永磁体和气隙区域用解析法求解,槽形区域用差分法计算.两区域共有部分的磁场计算结果作为另一个场域的边界条件.真实反映气隙磁场的切向和径向磁密,由此可准确计算定子开槽后的定位转矩.实例计算与有限元计算较好地吻合,从而验证了该方法的正确性.

A semi-analytical approach with vector magnetic potential was applied for permanet-magnet air-gap field and cogging torque of stator slot. Analytical method was used to solve the air-gap field and permanent magnet while a difference method was used to solve the field equation in slot region. Computation results in common parts can be used as boundary condition for another region. It can reflect tangential and radial flux density correctly,which does good to the calculation of cogging torque.The proposed approach is verified to be correct and effective compared with the finite element method.
