Abstract

The decoupling control of torque and radial suspension forces is the key technology of the stable operation for a bearingless induction motor. In the paper, the principle of bearingless induction motor is expounded. The mathematics models of radial suspension force and the rotation part on a bearingless induction motor are given. A control system based on rotor magnetic field oriented control is designed. The control system is simulated with Matlab software. The simulation results have shown that the rotor can be suspended steadily, torque and radial suspension subsystems can be controlled independently, the control method is valid and the control system has good static and dynamic performance.
