Abstract
A superconducting rotating machine has a relatively compact construction while still providing a relatively high output power, thus the superconducting rotating machine has an increased power density characteristic. The superconducting rotating machine includes a stator assembly, a rotor assembly configured to rotate within the stator assembly and having at least one HTS superconducting winding assembly which, in operation, generates a magnetic flux linking the rotor assembly to the stator assembly, and a refrigeration system for cooling the at least one superconducting winding. The superconducting rotating has a gap shear characteristic greater than 10 psi.
