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.

新型磁通切换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开关直线电机的优点，提出了磁通开关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，通过三维 (3-D) 有限元法 (FEM) 对简化的 FSTFPMLM 的磁场进行数值计算。第三，对机器的推力特性，包括推力、齿槽力和力脉动进行了数值分析。通过三维有限元分析了结构参数对推力特性的影响。推力、齿槽力和力脉动规律作为初级和次级之间的极距比，以及次级变量的齿宽和极距之间的比值，为设计FSTFPMLM提供了指导，旨在实现更大的推力，使用更少的永磁材料，实现更小的齿槽效应和力波动。 FSTFPMLM 的推力能力与其他线性机器拓扑进行了比较。最后开发了样机和实验装置，计算结果与测量结果吻合良好。
