摘　　要：介绍电磁轴承磁场计算和转子受力特性分析的磁路法和有限元法。基于上述两种方法,详细地计算了考虑铁磁材料磁阻及其非线性因数的电磁轴承磁场,讨论了两种方法计算结果的差异。参考有限元法的计算结果,对计算电磁轴承磁场的磁路法进行了优化。优化后的电磁轴承磁路法简单、准确,具有工程应用价值。Magnetic cricuit method and finite element method in calculating magnetic field of electromagnetic bearing and analyzing force characteristics were introduced. The magnetic field considering permeability and nonlinear has been calculated detailedy and the difference of two calculation results has been discussed. This work optimized the magnetic circuit method in calculating magnetic field of electromagnetic bearing based on the results of FEM. The optimized magnetic circuit method is simple and accurate and also very useful in developing engineering application of electromagnetic bearing.
