Thermal design of superconducting cryogenic rotor: Solutions to conduction cooling challenges

This paper describes the design and testing of first cryogenic rotor based on conductively cooled superconducting stacked tape pseudo bulks used in a rotating machine with various magnetisation methods. The demanded number unusual features constraints that required novel, innovative solutions may be applicable other designs. aim this work is not to create complete manual, rather, suggest some ideas could useful others who are looking solve similar problems. outline proposed followed by detailed description key systems their interactions. Several characteristics discussed, including calculation liquid cooling. Finally, experimental thermal results indicate calculations reliable provide reaffirmation overall success design.
