An Experimental Alternator With A Superconducting Rotating Field Winding

Abstract
This paper describes the design, fabrication, and testing of a two-pole, 3600 r/min, three-phase, 80 kVA alternator with a rotating, super-conducting field winding and an air-cooled copper armature. The major contribution is the experimental proof that liquid helium can be used in a rotating dewar vessel to successfully cool a rotating, superconducting field winding.
