400kW class axial gap-type motor for ship propulsion system consists of HTS armature winding and permanent magnets have developed by industry - university collaborative research group (IHI, Fuji Electric, Hitachi, Nakashima Propeller, Niigata Power System, Sumitomo Electric, Taiyo Nippon Sanso and University of Fukui). Sumitomo Electric has also developed prototype electric vehicle equipped with a DC motor including HTS field winding. In these cases, bismuth based superconducting wire (DI-BSCCO) were used for HTS windings and cooled down by liquid nitrogen. In order to realize high power and compact motor, operating temperature, current density, and electrical, mechanical and thermal performance under the magnetic field should be considered. Current status of these developments will be presented and wire requirements for future rotating machine applications will be also mentioned.
