摘要

摘要: 永磁偏置型磁悬浮轴承中既存在永磁磁场,又存在电磁磁场,其结构及磁场分布比较复杂,涉及的参数也较多,利用简单的等效磁路法无法对所有的参数进行精确设计。以一种结构形式的永磁偏置型径向磁悬浮轴承为例,在分析其工作原理及磁场分布的基础上,提出了一种基于磁通量计算的参数设计方法,给出了设计流程与计算实例。利用有限元分析软件对设计结果进行了电磁场仿真。实验结果表明:基于此方法设计出的永磁偏置型径向磁悬浮轴承具有良好的悬浮特性。给出了转轴在20 000 r/min时的径向位移波形及控制绕组中的电流波形。

Abstract: There is not only permanent magnetic field but also electric magnetic field in permanent magnet biased magnetic bearing so that its mechanism and magnetic field distribution are always complex and a lot of parameters are involved. Taking a kind of permanent magnet biased radial magnetic bearing as an example; a parameter design method based on magnetic flux calculation is advanced in this paper after analyzing its operational principle and magnetic field distribution; and the designing flow and calculation illustrations are presented. Magnetic field simulation of the design result is operated by using the finite element analysis( FEA) software. The experimentation results testify that the permanent magnet biased radial magnetic bearing designed by this method has good levitation performance. The radial displacement and control current curves at 20 000 r/min are also presented.
