Patent ID: 7728466

Claim:
A superconducting technology machine, comprising: a stator; and a rotor enclosed by the stator, the rotor being mounted so as to rotate about a rotor axis with an air gap between the stator and the rotor, the rotor comprising: a cold part containing superconductors of a rotor winding; a warm housing having an outer wall facing the air gap, the warm housing being thermally insulated from the cold part; a dampener shield provided on the outer wall of the warm housing; and support elements provided at predetermined positions between the warm housing and the cold part, the support elements extending in a radial direction between the warm housing and the cold part such that: there is a small distance respectively formed between the support elements and the warm housing in a normal operating condition of the machine in which the warm housing is deformed less than or equal to a predetermined amount, and there is a force-fit between the warm housing and the cold part via the support elements only in a stressed condition of the machine in which the warm housing is deformed greater than the predetermined amount.
