Patent ID: 7667366

Claim:
A rotor for an electric generator, the rotor comprising: a rotor core defining a first and a second axially extending flat surface region, each of the first and the second flat surface regions bounded by first and second opposing edges; a superconducting winding circumscribing the rotor core, axial segments of the superconducting winding disposed within the first and the second flat surface regions; a plurality of first and a plurality of second core extension elements mating with the respective first edge of the first and the second flat surface regions; a first arcuate shield extending axially along the rotor core enclosing the axial segment within the first flat surface region, the first shield having a first axial edge mating with a first edge of the plurality of first core extension elements and a second axial edge mating with the second edge of the first flat surface region; and a second arcuate shield extending axially along the rotor core enclosing the axial segment within the second flat surface region, the second shield having a first axial edge mating with a first edge of the plurality of second extension elements and a second axial edge mating with the second edge of the second flat surface region.
