摘　　要：该文通过在计算中引入复数气隙比磁导,对传统广义磁路法中的气隙磁阻进行了修正,并将改进的广义磁路法应用于表贴式永磁电机的空载气隙磁场解析计算,能够同时考虑到磁路饱和、铁磁材料非线性以及定子开槽的影响。该文提出的解析计算方法与有限元仿真结果吻合,实验测试进一步验证了改进的广义磁路法的有效性和准确性。In this paper, the air gap reluctance in the traditional generalized magnetic circuit method is modified by introducing the complex air gap relative permeance in the calculation. The improved generalized magnetic circuit method can be applied to analyze the no-load air gap magnetic field of the surface-mounted permanent magnet motor, which can consider the influence of magnetic circuit saturation, ferromagnetic material nonlinearity and stator slotting at the same time. The analytical calculation method proposed in this paper is consistent with the finite element simulation results. Experimental tests further verify the effectiveness and accuracy of the improved generalized magnetic circuit method.
