Abstract
Various embodiments are directed to a high temperature superconducting (HTS) synchronous machine having a rotating armature and methods for fabricating the same. The HTS synchronous machines described herein solve the rotating seal system complications which plague conventional HTS synchronous machines by eliminating entirely the need for any such system. Instead, it is proposed here to rotate the AC armature windings, which are stationary (i.e., normally the “stator”) in conventional HTS synchronous machines, while allowing the superconducting field windings to remain stationary.
