Abstract
A rotor assembly includes a superconducting winding assembly positioned within a cryogenic region of the rotor assembly. In operation, the superconducting winding assembly generates a magnetic flux linking a stator assembly. The rotor assembly also includes a torque transfer assembly that includes first and second tubes that are positioned in a radial space external to the superconducting winding assembly and that extend along a longitudinal axis of the rotor assembly.
