Patent ID: 7256523

Claim:
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-T c 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 in a direction substantially perpendicular to the bearing gap while maintaining the seal; wherein said sealing means comprises annular sealing elements which seal off in relation to one of the rotor shaft and said first bearing part; wherein the stator is disposed inside a stator housing, and wherein the annular sealing elements are held on the stator housing at a portion having sufficient elasticity.
