Outline of Final Research Achievements

We have studied on key points to verify the operation of superconducting ship propulsion motor on board by using a research vessel“Umitaka-maru" with conventional motor. Based on the on-board data, we focused on the heat load capability and electromagnetic force applied to field pole winding of superconducting wire cooled down. The laboratory and on-board testing for cooling are comparatively discussed. In conclusion, we have obtained requested information and knowledge on the heat load survivability for on-board operation of the motor. The obtained result would provide a useful basis to practical application of superconducting ship propulsion.
