Abstract
The superconducting electric propulsion system using superconducting motor seems to be an ideal propulsion system for the future. We have constructed a 480kW superconducting DC homopolar motor for the purpose of developing this new system. This motor is composed of superconducting field winding, segmented armature drum and copper-graphite current brushes. The superconducting field winding is cooled by the condensation heat exchangers and helium refrigerating system being built into the cryostat. We have obtained good test results that operating parameters of this DC homopolar motor accorded with the design parameters.
