A magnetic bearing having a first bearing ring and a second bearing ring arranged concentrically in relation to the first bearing ring. The first bearing ring and the second bearing ring are mounted so as to be rotatable with respect to each other about an axis of rotation by means of electromagnets. The first bearing ring has a first magnet row and a second magnet row. The magnet rows each include electromagnets arranged at a distance from one another in a circumferential direction of the first bearing ring. The electromagnets of the magnet rows are oriented such that they can each exert a magnetic force on the second bearing ring, which magnetic force is oriented transversely to the axis of rotation and transversely to a radial plane which is arranged perpendicularly to the axis of rotation.

Magnetic bearing and method for operating a magnetic bearing

A magnetic bearing may include an inner ring and an outer ring arranged concentrically. The inner ring and the outer ring may be mounted rotatably relative to each other by way of axial and radial magnets. The magnetic bearing may also include a back-up bearing, which is integrated into at least one of the outer ring or the inner ring both in an axial direction and in a radial direction. The outer ring may be multipiece and may include a recess that opens inwards and receives the inner ring. Further, the back-up bearing may be made of aluminum, austenitic steel, bronze, or ceramic, and the back-up bearing may operate as a shielding device that shields magnetic fields emitted by the axial and radial magnets from one another.
