## New permanent magnet biased radial magnetic bearing in magnetic suspending flywheel application

• 摘要: 为了克服现有永磁偏置径向混合磁轴承的缺陷,提出了一种磁悬浮飞轮用新型永磁偏置径向混合磁轴承,分析了其工作原理,并分别利用等效磁路法及有限元方法对该永磁偏置径向混合磁轴承进行了电磁分析.分析结果表明:所提出的新型永磁偏置径向混合磁轴承采用永磁磁场作为偏置磁场,并且其永磁磁路与电励磁磁路在任一径向截面中共面,可使磁轴承轴向长度大为减小,与现有永磁偏置径向混合磁轴承相比具有体积更小的优点,同时该种永磁偏置径向混合磁轴承产生的偏置磁场在X,Y方向上不会产生耦合,可使控制更加容易,特别适用于高速、低功耗等场合.
