摘　　要：以电磁主动控制型磁轴承为研究对象,在论述磁轴承结构特点的基础上,推导了磁轴承的动力学方程;重点介绍了磁轴承设计中的关键参数轴向电磁力和径向电磁力的计算方法,给出了其电压方程;从机电磁一体化角度,建立了磁轴承的动态模型,并进行了分析。本文中所涉及的问题对其它类型的磁轴承设计有参考价值。Taken magnetic bearing as the research object and based on the summary of characteristics of magnetic bearing, the dynamic equation of magnetic bearing is inferred. Emphasis is put on the calculating methods of radial and axial electromagnetic force, the crucial parameters in designing magnetic bearing. The voltage equation is given. Lastly, based on machine and electricity and magnetism, the dynamic model of magnetic bearing is set up and analyzed. Some contents involved in this paper are of referential value for other magnetic bearings.
