摘　　要：横向磁通永磁直线电机具有力密度高和控制特性好的优点,但推力波动较大也是一个不容忽视的问题,为此提出了一种定子单元铁心轴向类分布排列的横向磁通永磁直线电机。本文首先介绍了原有横向磁通永磁直线电机的结构及工作原理;在此基础上,提出了一种新型定子单元铁心轴向类分布排列方式,通过理论分析及数值计算研究了其对电机反电动势、定位力和电磁力的影响,同时对不同定子单元铁心轴向类分布排列方式进行了对比分析。研究结果表明,采用定子单元铁心轴向类分布排列方式可以有效抑制电机的推力波动。This paper proposed a transverse flux permanent magnet linear machine （PMLM） with the class distribution of the stator core group arrangement in the axial direction, due to the problem of larger thrust force ripple in transverse flux PMLM, which has some merits higher force density and better controllable characteristic etc. Firstly, the structure and operating principle of transverse flux PMLM was presented. Secondly, the influence of the class distribution of the stator core group arrangement on the motor performance is analyzed in detail. Special attention was paid to the back-EMF, cogging force and electromagnetic force etc. The paper investigated the influence of different arrangements in transverse flux PMLM, including theoretical analysis and numerical calculation. The results show that the thrust ripple can be decreased by the class distribution of the stator core group arrangement in transverse flux PMLM.
