摘　　要：永磁传动技术可实现"零泄漏"的绝对密封,利于这一特点,可广泛应用在真空设备中以获得高洁净度、高真空度的作业环境。本文首先阐述了永磁传动原理,针对永磁驱动技术在真空设备动密封的应用,综述了关键技术的研究现状,介绍磁力驱动技术在真空获得设备、真空工程技术、真空机器人领域的应用,最后就真空磁力驱动动密封技术今后的研究与发展方向进行了探讨。The latest progress in the development of permanent magnetic driving（PMD）technology for vacuum dynamic sealing and its wider applications was tentatively reviewed. The discussions included but were not limited to： i） its operating principle and teehnological strengthens; ii）major research projects of PMD technology centered on its applieation in zero leakage sealing of a variety of vacuum systems; and iii） its increasingly wider applications in the fields of pumping equipment, vacuum engineering technology, and vacuum robot fabrication technology not only because of its capability of ensuring a highly clean and high vacuum environmenthut also because of its environmental friendliness. The development trends, research scenarios, and major problems of PMD technology were also briefly discussed in a thought provoking way.
