利用有限元法分析电磁推力轴承的磁场分布情况及电磁力变化规律。在两种不同的加载方式下,计算对比由内、外环磁极面积比变化而产生的不同电磁力,为轴承的结构设计提供理论依据。
The magnetic field distribution and electromagnetic forces are analyzed for an electromagnetic thrust bearing based on finite element method. The different electromagnetic forces are acquired by offering different loads and different area ratio of inner and outer magnetic poles. The research can provide logical proofs for the structural design of the electromagnetic thrust bearing.
