Abstract
A superconducting electrical machine includes a rotor and a stator. The stator defines a cavity. The rotor is configured to rotate about a longitudinal axis. The rotor is disposed at least partially within the cavity. The rotor includes a shaft configured to rotate with the rotor, a rotor active section including at least a rotor torque tube and a superconductor, and a first re-entrant end attaching the shaft to the rotor active section. At most a threshold fraction of a bending force applied to the shaft is communicated to the rotor active section.
