To solve the problem of bearingless induction motor’ unbalance vibration that is caused by rotor mass eccentricity, the generation mechanisms of unbalanced exciting force and unbalanced vibration displacement are analyzed firstly. Then, the extraction method of unbalanced radial displacement based on LMS algorithm is presented, and the compensation strategy of unbalanced exciting force is researched. By real-time regulation and calculation, the compensation forces of unbalanced vibration and unilateral magnetic pull are achieved, and the impacts of unbalanced exciting force and unilateral magnetic pull are compensated. Simulation results of the unbalance vibration control system have shown that the amplitude of unbalance vibration can be greatly inhibited, and the suspension control precision of bearingless rotor can be improved greatly.
