ABSTRACT:
The apparatus uses an influence coefficient calculating method to allow a rotor supported on active magnetic bearings to rotate about an inertial axis which, due to possible imbalances in the rotor, may be different from the geometric axis of the rotor, without transmitting imbalance forces to the housing of the active magnetic bearings.
