Abstract
A generator rotor core (54) carrying superconducting windings (60) and having a shield (426) over the superconducting windings (60) to prevent external magnetic fields from impinging the windings. Axial shield edges (430/434) mate with corresponding features of the rotor core (54) or with structures affixed to or supported by the core (54) to support the shield (426).
