永磁同步传动系统的应用概况

Application Status of Permanent Magnet Synchronous Drive System

概述了永磁材料的发展概况以及永磁同步电机的特点。永磁同步电机以其体积小、重量轻、功率密度高等特点在交流传动系统得到了越来越广泛的关注,应用领域不断扩大。文章介绍了永磁同步电机在轨道交通牵引系统、钻机顶部驱动系统、流程工业传动系统及船舶推进系统中的应用状况。

It summarizes the development status of permanent magnet material and the characteristics of permanent magnet synchronous motor （PMSM）. PMSM has been paid close attention and used widely in AC driving system for its characteristics such as low volume, light weight and high power density. It presents the application status of permanent magnet synchronous drive system in railway vehicle traction system, top driving system of drill machine, process industry drive system and ship propulsion system.
