摘　　要：在对无轴承交流电机的磁悬浮机理进行一般性描述的基础上,采用电枢绕组气隙磁场定向控制来实现转矩控制和悬浮力控制之间的动态解耦,并以无轴承鼠笼式异步电动机为研究对象,研制了一套控制系统,并在原理样机上进行实验,实现了转子轴的稳定悬浮,而且动态性能良好,验证了提出的无轴承异步电动机控制系统的可行性.Based on the introduction of the suspension principle of bearingless induction motor, the armature winding air-gap-flux-oriented vector control is applied to realize the decoupling control between electromagnet torque control and radial suspension force control. Aiming at squirrel cage induction type bearingless motor, a control system is accomplished and tested on the test machine. The experimental results show that laboratory bearingless induction motor is successfully suspended and can be operated stably as well as transient conditions. The feasibility of the proposed bearingless induction motor control system is proved.
