提出了混合磁轴承的混合因子。混合因子定义为混合磁轴承中永磁体产生的力与永磁体和电流产生的力的比值。首先从径向混合磁轴承的电流刚度和位移刚度等重要参数出发，推导出径向混合磁轴承的刚度，建立了磁悬浮转子系统的动力学模型。基于混合因子分析了结构参数与控制系统参数之间的关系。分析了永磁体尺寸、气隙长度、定子磁极面积等因素对混合磁轴承混合系数的影响。根据上述混合因子的定义，可以得出较小的功率损耗可以导致较大的混合因子。同时，混合因子存在一个最大值，该值除与结构参数有关外，还与比例因子等控制系统参数有关。最后，总结了混合磁轴承参数的设计步骤。
In this article, hybrid factor is proposed for hybrid magnetic bearing. The hybrid factor is defined as the ratio of the force produced by the permanent magnet and the forces produced by the permanent magnet and current in hybrid magnetic bearing. It is deduced from a certain radial hybrid magnetic bearing using its important parameters such as the current stiffness and displacement stiffness at first and then the dynamic model of magnetically suspended rotor system is established. The relationship between structural parameters and control system parameters is analyzed based on the hybrid factor. Some influencing factors of hybrid factor in hybrid magnetic bearing, such as the size of the permanent magnet, length of air gap, and area of the stator poles, are analyzed in this article. It can be concluded that larger hybrid factor can be caused by the smaller power loss according to the definition of hybrid factor mentioned above. Meanwhile, the hybrid factor has a maximum value, which is related to control system parameters such as proportional factor expect for structural parameters. Finally, the design steps of parameters of hybrid magnetic bearing can be concluded.
