Abstract
The invention relates to a magnetic bearing assembly of a rotor in a stator, with at least one magnetic bearing ( ) comprising a stator part ( ) and a rotor part ( ) arranged coaxially thereto in the operating position without contacting the stator part. The bearing effective area of the rotor part is formed by a radial exciting system ( ) having a permanent magnet ( ), while the stator part ( ) comprises a high-temperature superconductor concentrically surrounding the radial exciting system ( ) while maintaining an annular air gap ( ). For increasing the specific rigidity of such a bearing, it is proposed according to the invention that the high-temperature superconductor is divided in at least two HTSC partial shells ( ) which, after the transition into the superconducting state, can be displaced against one another by an actuator ( ) in the radial direction from a position in the hot state of the bearing, in which each HTSC partial shell ( ) has a first radial spacing ( ) from the radial exciting system ( ), into a working position with a second, smaller radial distance (operating gap ( )from the radial exciting system ( ).
