Abstract: 　　The control of the constant phase difference between the current and the displacement of the magnetic damper in rotor-bearing system is studied. First, relation among the magnetic control force, control currents and displacement of rotors is presented. Then, taking a symmetrical single disk rotor-bearing system, the vibration equation of the system cntrolled by a magnetic damper is described, and the force response is solved. Finaly, an example is calculated and conclusions are obtained.
