摘 要： This paper presents a five-degrees-of-freedom (DOF) magnetic levitation motor system. The rotor of the system is rotated by a high speed induction motor. In order to improve the integration level, reduce the volume and power loss of the system, one hybrid axial-radial magnetic bearing and one hybrid radial magnetic bearing are applied to suspend the rotor. These two kinds of hybrid magnetic bearings are similar in structures so that the work amount of parameters and mechanical parts design can be reduced. The structures and working principles of these two hybrid magnetic bearings are presented in this paper. The finite element simulations of electromagnetic fields are performed by ANSYS. The experimental prototype is designed and stable suspension of the rotor in 20000 rpm is realized. According to the advantages of this kind of magnetic bearing system, it can be used in those fields having high demands on volume and power consumption such as aeronautics, astronautics and energy storage systems etc.

本文提出了一种五自由度（DOF）磁悬浮电机系统。该系统的转子由高速感应电机驱动旋转。为了提高集成度、减小系统体积和功率损耗，采用了一种混合轴向-径向磁轴承和一种混合径向磁轴承来悬挂转子。这两种混合磁轴承结构相似，可减少参数设计和机械部件设计的工作量。本文介绍了这两种混合磁轴承的结构与工作原理，并通过ANSYS进行了电磁场的有限元仿真。同时设计了实验原型，实现了转子在20000转/分钟下的稳定悬浮。鉴于此类磁轴承系统的优点，其可广泛应用于对体积和功耗要求较高的领域，如航空航天、航天以及储能系统等。
