Description

ABSTRACT:
A rotor assembly for use within a superconducting electric motor includes a superconducting winding formed of high temperature superconductor and during operation, generates a flux path within the rotor assembly; and a high permeability magnetic material, positioned within at least a portion of the flux path so as to decrease the overall reluctance of the flux path. The rotor assembly may include a support member having an internal volume and formed of a non-magnetic, high-strength resilient material. The support member supports on its outer surface the superconducting winding and within its internal volume, the high permeability magnetic material. The magnetic material may be in the form of a core member to provide the low reluctance portion to the flux path generated by the superconducting winding.
