ABSTRACT:
A superconducting field winding assemblage for an electrical machine, such as a rotary generator or a linear motor. The field winding assemblage includes at least two pole assemblies. Each pole assembly has a direction of motion, a solid core, a superconductive coil assembly generally surrounding the solid core, and a first cooling conduit. The superconductive coil assembly has a generally longitudinally extending axis positioned generally perpendicular to the direction of motion and has an epoxy-impregnated, generally racetrack-shaped superconductive coil having a minor axis positioned generally parallel to the direction of motion. The first cooling tube contains a gaseous cryogen (such as gaseous helium) and is positioned to be in thermal contact with the superconductive coil.
