%X 摘要： 针对径向磁轴承,以实际工程经验为基础给出气隙、磁极、转子、定子、磁极面积、线圈等的设计原则,并设计不同转子直径和不同磁极数的径向磁轴承结构。利用有限元分析软件对设计的径向磁轴承进行电磁场仿真分析,得到磁场分布和电磁力。根据仿真结果研究不同转子直径下,磁极数对轴承承载力的影响。仿真结果表明,当转子直径不超过150 mm时,径向磁轴承的承载力随着磁极数的增加显著减小。当转子直径达到150 mm后,磁极数对径向磁轴承的承载力并无明显的影响。<br>Abstract: The design principles of air gap, magnetic pole, rotor, stator, magnetic pole area and coil were given on the basis of practical engineering experiences. The structures of radial magnetic bearing with different rotor diameter and different magnetic pole number were designed. The finite element analysis software was used to simulate the electromagnetic field of radial magnetic bearing. The electromagnetic force and the magnetic field distribution were obtained. According to the simulation results, the influence of the number of poles on the bearing capacity of bearings under different rotor diameters was studied. The simulation results showed that the capacity of the radial magnetic bearing decreased significantly with the increase of the number of poles when the rotor diameter did not exceed 150 mm. While, the number of poles did not have a significant effect on the capacity of radial magnetic bearings when the rotor diameter reached 150 mm
