Magnetic bearing

Abstract

Abstract The invention relates to the magnetic bearing of a rotor in a stator, in which one bearing part is permanently magnetic and the rotor is stabilised in its nominal axis of rotation in the magnetic field, without making contact. According to the invention, the bearing part which is not permanently magnetic consists of super-conducting material. To this end, a cooling device is provided for cooling the bearing part consisting of super-conducting material, by means of which a temperature can be set below the transition temperature of the super-conductor. In one of the embodiments of the magnetic bearing, the stator consists of super-conducting material and has a perforating cylindrical hole. The associated rotor is positioned in the region of the hole and consists of at least one permanent magnet with magnetic poles located on the rotor axis. <IMAGE>
