摘　　要：分析了横向磁场电机的电磁力产生原理,并对高转矩密度机理进行了讨论;总结了不同类型横向磁场电机的结构、特点及目前的发展状况,并对其控制技术进行了分析;针对电机在结构设计、性能分析等方面遇到的问题,探讨了横向磁场电机的研究方向和发展趋势。指出:横向磁场电机在结构上实现了电磁解耦,可以通过提高极对数来提高转矩密度,而且各相解耦使控制方法大大简化,因而特别适合于多极、低速大转矩的应用领域,应用前景广阔,但结构复杂、功率因数低等技术问题亟待研究解决。In this paper, the operating principles of transverse flux machines （TFMs） are analyzed in detail and magnification principles are investigated. The state-of-art of the machines＇ topological structures and their torque features are overviewed and their control strategies are analyzed. Finally, the current problems of TEMs in structure design, performance analysis, etc. and the development trends of TFMs are brought out. It is pointed out that TFMs have a brilliant prospect in low speed, direct drive systems for their favorable features of high torque density, diverse topological stmctures, etc,
