Active vibration control of an induction motor with sleeve bearings and electrodynamic actuators between motor feet and steel frame foundation regarding electromagnetic excitation

  • The paper presents a theoretical analysis of active vibration control of an induction motor with sleeve bearings and electrodynamic actuators between motor feet and steel frame foundation, where the vertical vibration velocities of the motor feet are lead back to separate controllers. Based on a 2D model, the mathematical coherences of the controlled vibration system are presented, as well as a numerical example of a 2-pole induction motor. The threshold of vibration stability is calculated as well as frequency responses regarding bearing housing vibrations caused by electromagnetic forces in the air gap of the induction motor, due to a static magnetic eccentricity between rotor and stator. Also the actuator forces are analyzed. With this analysis, the effectiveness of the developed active vibration control system can be demonstrated.
