摘　　要：横向磁通开关磁链永磁直线电机的磁通路径与电枢绕组中的电流在空间上相互垂直,实现了电负荷与磁负荷的解耦,从而使其力密度得到提高.针对横向磁通开关磁链永磁直线电机,本文阐述了横向磁通永磁直线电机的磁路结构和工作原理,提出了几种拓扑结构.通过有限元数值计算分析并对比了不同拓扑结构电机的气隙磁场分布、绕组磁链、反电势等特性曲线,为确定最佳拓扑结构奠定了基础.The magnetic flow route of transverse flux flux-switching permanent magnet linear machine is mutually perpendicular to current in armature winding in space,which has realized decoupling of electrical load and magnetic load,so that its force density is improved. Aiming at transverse flux switching flux linkage permanent magnet linear motor,the magnetic circuit structure and working principles of transverse flux permanent magnet linear motor were described,and several topological structures were put forward. The characteristic curves of air gap magnetic field distribution,winding flux linkage and back-EMF of different topology motors were analyzed and compared by finite element numerical calculation,which lays the foundation for determining the best topology structure.
