无轴承同步磁阻电机除了具有一般无轴承电机的优点外,还具有结构简单、成本低、损耗小以及易于实现高速运行等优势,在真空、高速、高精等工业领域具有广阔的应用前景。该文首先介绍了无轴承同步磁阻电机的转矩与悬浮力产生原理,然后针对国内外无轴承同步磁阻电机已开展的研究工作,从电机样机优化设计和控制系统研究两方面进行综述,最后根据无轴承电机高转速、高精度和低成本的发展方向,展望了无轴承同步磁阻电机未来研究的发展趋势。

Besides the advantages of the normal bearingless motor, a bearingless synchronous reluctance motor （BSynRM） has the advantages of simple structure, low cost, low loss and can realize high speed operation. So the BSynRM has broad application prospects in vacuum, high speed, high precision and many other industrial fields. The principles of torque and suspension force generation of the BSynRM were described firstly. Then, researches about the BSynRM were summarized through two aspects： the optimum design of motor prototype and the researches of the BSynRM control system. Finally, the trends of the BSynRM were analyzed based on the bearingless motor development directions of high speed, high precision and low cost.
