摘要

针对一种混合充磁式磁齿轮复合电机的损耗进行了研究，对比分析混合充磁式磁齿轮复合电机和径向充磁式磁齿轮复合电机的磁场和气隙磁通密度及其谐波，得到了不同转速下两种磁齿轮复合电机的铁耗和涡流损耗情况，并对调磁块形状进行了优化。结果表明，与径向充磁式磁齿轮复合电机相比，混合充磁式磁齿轮复合电机铁耗更小，产生的磁场强度更强，内层和中层气隙磁通密度更大，外层径向磁通密度和切向磁通密度的谐波幅值相对较小，有助于减少涡流损耗；优化后的圆形调磁块结构，可以减小复合电机的涡流损耗和铁耗。

Abstract

The loss of a hybrid magnetized magnetic gear composite motor is studied， and the magnetic field and air gap magnetic density and harmonics of the hybrid magnetized magnetic gear composite motor and the radial magnetized magnetic gear composite motor are compared and analyzed. The iron loss and eddy current loss of the two magnetic gear compound motors at different speeds are obtained， and the shape of the magnetic adjustment block is optimized. The results show that， compared with the radial magnetized magnetic gear composite motor， the hybrid magnetized magnetic gear composite motor has lower iron loss， stronger magnetic field strength， and greater inner and middle air gap magnetic density. The harmonic amplitude of the outer radial magnetic flux and tangential magnetic flux is relatively small， which helps to reduce the eddy current loss， and the optimized circular magnetic modulation block structure can reduce the eddy current loss and iron loss of the composite motor.
