中文摘要：

目前磁力驱动技术应用于旋转类机械传动时，在高速、大间隙条件下动力电机极易损坏，无法保证其长时间运行。针对这些实际存在的问题，提出了一种行波磁场驱动的磁力传动方式。阐述了该系统的结构特点和实现方案，分析了主动磁极（电磁体）和从动磁极（永磁体）之间的相对运动状态关系，确定了永磁体转动过程中电磁体4个磁极状态的切换，设计了系统的传动方案和3种驱动方案，在此基础上对各种驱动方案所产生的空间磁场进行了实验研究，确定了驱动能力较强的大间隙磁力传动系统方案，磁极间隙可达到60mm。

英文摘要：

When magnetic drive technology is used to rotating machinery＇s transmission, its power motor is damaged easily at high speed and large gap. Aiming at these actual problems, we present a magnetic drive mode which is driven by traveling wave magnetic field. We explained in detail the system＇s structure and its realization, arialyzed the movement state＇s relation between the active magnetic pole （electromagnet） and the passive magnetic pole （ permanent magnet）, determined the four magnetic pole state switches of the electromagnet in the rotation process of the permanent magnet, and designed the system＇s transmission scheme and three drive schemes. In addition, we canT out experimental study on the space magnetic field which is produced by these drive schemes, and confirm the large gap magnetic drive system＇s scheme whose drive ability is stronger. The gap of magnetic pole can be 60 mm.
