Abstract
A thrust disc for a magnetic bearing, wherein the thrust disc comprises: a body, which is adapted to be mounted on a shaft and which has a first offset yield strength and a first magnetic permeability, and at least one flange which is fixed to the body in a position where it can interact with a thrust stator in order to form a magnetic bearing and which has a second offset yield strength and a second magnetic permeability; wherein the first offset yield strength is higher than the second offset yield strength; and wherein the first magnetic permeability is smaller than the second magnetic permeability. Additionally, the magnetic bearing can be equipped with such a thrust disc. An apparatus can be equipped with such a magnetic bearing.
