ABSTRACT:
Radial, soft magnetic rotor disk elements which engage in each other and soft magnetic stator disk elements form a magnetic bearing device. The elements are provided with teeth-like extensions which are arranged opposite to each other over an air gap on sides which are oriented towards each other. Magnetic fields, which may be produced by permanent magnets or electromagnets, are assigned to the stator disk elements to produce a magnetic maintaining flow which is oriented in an axial direction between the disk elements for radial adjustment. An electromagnetic winding is also provided in the region of the central plane of the bearing device for axial adjustment, which enables a magnetic control flow, which superimposes the magnetic maintaining flow, to be produced.
