Abstract
A superconducting dynamoelectric machine has a cryogenic portion of the rotor supported on the ambient temperature portion of the rotor by relatively long and thin spokes. The spokes extend between the ambient temperature portion and a flange located on a cryogenic temperature portion. The materials of the flange and spokes are selected so that contraction of the spokes along their length will be compensated for by contraction of the flange in that direction. Contraction in the transverse direction is compensated for by an appropriate displacement of the end of the spoke connected to the ambient temperature portion. Alignment and tension of the spoke is accurately achieved by an appropriate adjusting arrangement.
