摘　　要：为了消除摩擦阻力并简化系统结构,实现多电航空发动机轴承的磁浮运行,设计了一种具有独立转矩和悬浮力极的动力磁浮轴承。采用有限元法对转矩及悬浮力特性进行分析,结果表明该轴承可以产生独立可控的转矩和悬浮力。搭建了试验平台,试验结果证明:运行过程中转子能够稳定地悬浮于中心位置,且转矩和悬浮力可以自然解耦,实现可控的磁悬浮运行。In order to eliminate frictional resistance, simplify system structure and realize magnetic suspension opera- tion of bearing for more - electric aeroengine, a power magnetic bearing with separated torque and suspension force poles are designed. The characteristics of torque and suspension force are analyzed by FEM. The results show that the bearing can generate torque and suspension force which could be controlled separately. The test platform is built. The test results prove that the rotor can be stably suspended in central position during operation process, and torque and suspension force are naturally decoupled. The controllable magnetic suspension operation can be realized.
