Magnetic mounting of a rotor shaft relative to a stator, using a high-Tc superconductor
First Claim
Patent Images
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.

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.
