Abstract
A magnetic bearing arrangement () for a motion element, having the following features: the magnetic bearing arrangement has a stator. The magnetic bearing arrangement has a passive magnetic bearing () for lateral guidance of the motion element () and a controllable magnetic bearing () for guidance of the motion element perpendicular to the guidance by way of the passive magnetic bearing. The controllable magnetic bearing has an electronic stabilization device; the stabilization device has an electrical conductor () that can have an electrical control current applied to it by the stabilization device and that is associated with the stator element () in such a way that the magnetization of the stator element is influenced by the control current. The controllable magnetic bearing has a permanent magnet (); the permanent magnet is arranged on the motion element opposite the stator element. The magnetic force between permanent magnet and stator element is dimensioned such that with a control current of zero, the motion element is held in the working position; and only upon deviation from that working position is a control current generated that influences the magnetization of the stator element in the direction of re-establishing the working position.
