ABSTRACT:
The rotor of an electric machine with a superconducting field winding has a hollow support structure with the superconducting winding, enclosed in a shrouding cylinder. Formed inside the shrouding cylinder, in the support structure, is a ring header communicating with the cooling ducts for the superconducting winding. In the internal cavity of the support structure is a trough for feeding the coolant communicating with the ring header in the large tooth area by means of radial holes spaced apart along the rotor axis, which receive heat-conductors with ducts for transferring the coolant from the trough to the ring header. On the periphery of the support structure, in the portion or sector of the support structure tooth, is formed a recess communicating with the ring header and having mounted therein other heat-conducting members extending in the radial direction and thermally insulated both from the support structure and from the heat-conductors.
