摘要
当电磁轴承设计有容错要求时,往往采用磁极独立驱动的方案,磁极的拓扑结构体现更加复杂多样化。本文以8极结构独立驱动的径向电磁轴承为研究对象,对电磁轴承定转子本体模型进行网格剖分,以变分原理和分片差值为基础的数值分析,来确定网格内各点的矢量磁位,得到了不同拓扑结构(全N(S)型、NSNS型和NNSS型)下,电磁轴承定转子磁极磁场分布,给出了这3种拓扑结构下转子和定子的二维磁力线分布图、磁通密度分布图以及转子和定子间气隙的磁密波形图,从而以磁场分布的角度,分析这3种拓扑结构电磁轴承对转子稳定悬浮的影响。
When the electromagnetic bearing design has the requirement of fault tolerance,the scheme of independent drive of magnetic poles is often adopted,and the topology of magnetic poles is more complex and diversified.8 pole structure based on the independent drive radial electromagnetic bearing as the research object,the magnetic bearing stator grid subdivision ontology model,based on the variational principle and divided difference of numerical analysis,to determine the vector magnetic potential of each point in the grid,the different topology(total N(S),NSNS and NNSS),electromagnetic bearing rotor pole magnetic field distribution of the three kinds of topology structure is given under the two-dimensional magnetic line of force distribution of the stator and rotor,the magnetic flux density distribution and the air gap between rotor and stator flux density waveform figure,with the Angle of the magnetic field distribution,The influence of the three topological electromagnetic bearings on the stable suspension of rotor is analyzed.
