Abstract
The current development status of an air core synchronous motor with high-temperature superconducting field coils is presented. The work described is part of a U.S. DoE Superconductivity Partnership Initiative award. The motor design features a topology with a combination of a modified conventional armature and a rotating four-pole superconducting field winding operating at a nominal temperature of 27 K. For testing purposes, an open-loop cryogenic system is adopted to supply helium gas to the rotor cryostat for maintaining the operating temperature of the superconducting field winding. The exhaust helium gas intercepts heat leak into the rotor cryostat before being vented. The motor is expected to deliver 125 horsepower (hp) at 1,800 rpm. Successful demonstration of the 125 hp motor will represent a major milestone in the process of developing commercial superconducting motors with integrated closed-loop cryogenic systems. Design objectives and results as well as current project status are discussed.
