ABSTRACT:
A high temperature superconducting rotor for a synchronous machine includes a high temperature superconducting field winding, a field winding support concentrically arranged about the high temperature superconducting field winding, and a thermal reserve concentrically arranged about the field winding support. The thermal reserve includes a thermally conductive material. The material is either electrically conductive, for example, aluminum, or electrically nonconductive, for example, ceramics such as beryllium oxide or alumina. The thermal reserve material includes segmentation in a direction normal to the rotor axis, along the rotor axis, neither, or both. The rotor includes a banding concentrically arranged about the thermal reserve. The banding includes an electrically conductive material, for example, steel, an electrically nonconductive material, for example, Kevlar, or both. The rotor includes an outer layer concentrically arranged about the thermal reserve. The outer layer includes a thermally nonconductive material.
