Abstract:
A magnetic radial bearing assembly of a rotor in a stator, having at least one magnetic bearing comprising:a stator part; a rotor part arranged coaxially with said stator part in an operating position without contacting said stator part; a radial exciting system having a permanent magnet and forming a bearing effective area of said rotor part; a high-temperature superconductor (HTSC) of said stator part concentrically surrounding said radial exciting system while maintaining an annular air gap, wherein said high-temperature superconductor is divided into at least two circle segment-shaped partial shells; and an actuator that displaces said at least two circle segment-shaped partial shells apart in a radial direction after a transition into a superconducting state; wherein said at least two circle segment-shaped partial shells are displaced from a position in a hot condition of said bearing, in which each HTSC partial shell has a first radial distance from said radial exciting system, into a working position with a second, smaller distance from said radial exciting system.
