1. A magnetic mounting of a rotor shaft relative to a stator, comprising:

  • a first bearing part arranged fixedly in terms of rotation on the rotor shaft, including permanent-magnetic elements arranged next to one another and having flux guide elements arranged therebetween;

    a second bearing part provided on the stator, including a structure formed of superconductive high-Tc material, said first and second bearing parts being separated by a bearing gap; and

    sealing means for providing a seal of the bearing gap against penetration of ambient air and for allowing movement of said first bearing part with respect to said second bearing part while maintaining the seal.
