摘　　要：永磁偏置径向磁轴承能够实现转子的径向两自由度悬浮,是应用最为广泛的永磁偏置磁轴承。对永磁偏置径向磁轴承的研究现状进行了详细阐述,将径向磁轴承分为同极性和异极性两类分别研究,分析其结构及工作原理,进行类比,并指出其应用场合。对其拓扑的未来发展进行了展望,结合应用场合提出了多种结构形式的永磁偏置径向磁轴承,低功耗、结构简单、加工安装方便、控制性能优越的磁轴承仍将是重点研究领域。Permanent magnet biased radial magnetic bearing （PRMB） which can achieve 2-D suspension of rotor, is the most widely used for the permanent magnet biased magnetic bearing. In this paper, the research status of permanent magnet biased radial magnetic bearing were expounded in detail. PRMB were sorted as homopolar and heterpolartwo types radial magnetic bearing. Their configurations and operating principles were studied. Same type＇s magnetic bearings were compared and where they can be applied was pointed out. Many PRMBs topologies were advanced. PRMB with low power consuming, simple structure and easy controlled will be a primary researching direction.
