Abstract

A first bearing part is arranged fixedly in terms of rotation on a rotor shaft with permanent magnetic elements arranged next to one another and flux guide elements arranged between them. A second bearing part, separated from the first bearing part by a bearing gap, is provided on the stator and has a structure formed of superconductive high-Tc material. The bearing gap is sealed against penetration of ambient air, but allows movement of the first bearing part with respect to the second bearing part while maintaining the seal.
