摘　　要：将解析法和有限元法相结合 ,利用有限元法得到确定不削角永磁电机计算极弧系数的普遍适用曲线 ,利用解析法将削角等效为气隙的增大 ,然后利用前面的曲线确定计算极弧系数。工程实际中的应用证明该工作是正确。In this paper,the analytical and FEM are combined to overcome this problem.The FEM is use to obtained the generally-used curve for determining the effective pole-arc coefficient of permanent magnet motors with normal permanent magnet pole.while the analytical method is used to consider the effects of cutting angle.The validity and correctness of this paper are proved by application to practical machines.
