Aiming at the rotor eccentricity of bearingless induction motor, the force acting on rotor is analyzed and the nonlinearity effect of the rotor eccentricity is compensated by the radial force feedback control. The simulation and experiment proved the radial force feedback control improves levitation performance of the bearingless motor system.
