Abstract
A magnetic bearing for generating magnetic forces. A configuration of electromagnetic poles and of permanent magnetic poles which, to the greatest possible extent, is planar enables the generation of a magnetic flux in the air gaps toward the rotor, also in the de-energized state. If this flux is modulated using a control flux, magnetic forces can be exerted upon the rotor for the purpose of providing magnetic support. This configuration makes it possible to provide magnetic bearings of a simple mechanical design.
