摘要：

In this paper, we propose the method to analyze the magnetization distribution in magnetoanisotropic materials by using the finite-element method considering. the improved variable magnetization and Stoner-Wohlfarth model By using this method, furthermore, the effect of, the eddy currents induced in permanent magnets was analyzed. From the analyzed result, it is clarified how the magnetization distribution affects. the performance of the surface permanent magnet-type motors.
