Superconductive exciter winding for the rotor of a turbogenerator and method of production

In a turbogenerator rotor having a hollow cylindrical body, the combination of winding support means disposed within the hollow cylindrical rotor body for supporting a superconductive winding, a plurality of intermediate cylinders comprising vibration damping and cold shielding cylinders disposed around said winding support means intermediate said winding support means and the cylindrical body of the rotor, said winding support means, being force-lockingly connected to the cylindrical rotor body through axially transposed articulating points on said intermediate cylinders yet being permitted resiliency thereat in radial direction, said winding support means comprising a support cylinder disposed within said intermediate cylinders and formed with axially extending slots uniformly distributed about the outer periphery thereof, said slots having respectively equal dimensions and having a content of respectively equal dimension and equal weight consisting of conductors formed at least partly of copper or superconductive material or both thereof, slot wedges covering said slots respectively at the outer peripheral surface of said support cylinder, and a bracing cylinder having a length equal to that of said support cylinder being coaxially disposed thereon in shrink fitting engagement therewith.
