Abstract

A magnetic bearing assembly for a rotor, including at least two actively regulated magnetic bearings for stabilizing the rotor in directions oriented substantially perpendicularly to one another and to the axis of rotation. The magnetic bearings define a bearing plane oriented perpendicularly to the axis. The rotor has a center of gravity situated at an axial distance from the bearing plane whereby tilting motions of the rotor about tilt-axes perpendicular to the axis of rotation can be sensed and counteracted.
