摘　　要：介绍了一种全悬浮永磁偏置磁悬浮轴承电机系统。该系统由永磁偏置轴向-径向磁悬浮轴承、永磁偏置径向磁悬浮轴承及高速电机组成,给出了两种磁悬浮轴承的结构并分析了其工作原理。实验证明由这两种磁悬浮轴承组成的磁悬浮轴承系统具有良好的悬浮性能,给出了20 000 r/min时转子铁心的位移波形以及控制绕组中的电流波形。A full levitation permanent magnet biased magnetic bearing motor system was introduced. It consists of a permanent magnet biased axial-radial magnetic bearing, a permanent magnet biased radial magnetic bearing and a high speed motor. Two kinds of magnetic bearings＇ configuration was introduced;their operating principle was analyzed also. The experimentation testifies that the magnetic bearing system consisting of these two types of magnetic bearings has good levita- tion performance. The displacement of rotor core and control current curves at 20 000 r/min were also presented.
