摘要

摘要: 针对横向磁场永磁电机（TFPM）普遍存在的自定位力矩大的问题，提出了一种新型四相平板式TFPM结构。利用ANSYS三维电磁场单元对电机模型的自定位力矩进行有限元分析，得到电机单相自定位力矩随转子旋转角度的变化曲线。通过傅里叶变换求得到使电机总体自定位力矩最小的定子错开角度，绘制了这种情况下电机总体自定位力矩变化曲线。对样机的单相与整体自定位力矩的最大值进行了测量，实验结果表明：四相定子依次错开45°电角度时电机整体自定位力矩峰值明显降低。

Abstract: A novel four-phase flat-type transverse flux permanent-magnet motor (TFPM) is presented in this paper. In order to solve the bigger cogging torque problem that the TFPM ubiquitously has, the finite element method is adopted to analyze the 3-D magnetic field and the cogging torque of the motor model. The one-phase's cogging torque changing curve with the rotor rotation angle is given. Then the motor stator stagger angle which corresponding to the smallest total cogging torque is calculated by Fourier transform, and the total cogging torque curve is given in this situation. A prototype was designed, and the maximum cogging torques of the single-phase and the prototype were measured. The experimental results verify that the total cogging torque of the motor prototype can be reduced clearly when the stator stagger angle is 45°.
