摘　　要：针对永磁偏置轴向磁悬浮轴承类型多样、拓扑结构复杂的特点,提出了基于气隙中轴向控制磁场分布的永磁偏置轴向磁悬浮轴承的类型划分方法。结合偏置磁场的极性分布,将永磁偏置轴向磁悬浮轴承划分为四种不同的类型。在此基础上提出了永磁偏置轴向磁悬浮轴承拓扑结构设计的方法,即根据各类型的特点可以设计出隶属于该类型的永磁偏置轴向磁悬浮轴承的定子磁极的形状、控制绕组的放置位置以及永磁体的放置位置与充磁方向。According to the characteristics of permanent biased axial magnetic bearing which are varied types and complex topological structures,a method to divide permanent biased axial magnetic bearings into different types according to the distribution of control magnetic field in air gaps was presented.Combined it with the polar distribution of bias magnetic field,permanent biased axial magnetic bearings were divided into four types.Based on it,a topological structure design method of permanent biased axial magnetic bearings was presented.According to the characteristics of each type,the topological structure of one permanent biased axial magnetic bearing can be schemed out.
