The flux-switching transverse-flux permanent magnet linear machine (FSTFPMLM) is proposed in this paper, combining the advantages of the transverse-flux linear machine and the flux-switching linear machine. First, the structure and operating principle of the FSTFPMLM is presented. Second, the magnetic field of a simplified FSTFPMLM is numerically computed by the three-dimensional (3-D) finite-element method (FEM). Third, the thrust characteristics of the machine, including the thrust force, cogging force, and force ripple, are numerically analyzed. The influence of structure parameters on the thrust characteristics has been analyzed by the 3-D FEM. The law of thrust, cogging force, and force ripple as the pole pitch ratio between primary and secondary, and the ratio between the tooth width and pole pitch of the secondary variable provides the guidance to design FSTFPMLM, which aims to achieve a larger thrust, smaller cogging and force ripple using less permanent magnet materials. The thrust force capabilities of FSTFPMLM are compared with other topologies of linear machines. Finally, the prototype and experimental setup have been developed, and the calculated results and the measured results are in good agreement.

新型磁通开关横向磁通永磁直线电机的研制与分析

本文结合横向磁通直线电机和磁通切换直线电机的优点，提出了磁通切换横向磁通永磁直线电机（FSTFPMLM）。首先，介绍了FSTFPMLM的结构和工作原理。其次，简化的 FSTFPMLM 的磁场通过三维 (3-D) 有限元方法 (FEM) 进行数值计算。第三，数值分析了机器的推力特性，包括推力、齿槽力和力脉动。通过3-D有限元分析了结构参数对推力特性的影响。推力、齿槽力和力纹波作为初级和次级极距比的定律，次变量的齿宽与极距之比为设计FSTFPMLM提供了指导，旨在使用较少的永磁材料实现更大的推力、更小的齿槽和力纹波。FSTFPMLM 的推力能力与线性机器的其他拓扑结构进行了比较。最后，研制了样机和实验装置，计算结果与实测结果吻合良好。
