SUPERCONDUCTING ROTATING ELECTRICAL MACHINE AND MANUFACTURING METHOD FOR HIGH TEMPERATURE SUPERCONDUCTING FILM THEREOF

摘要

The present disclosure relates to a superconducting rotating electrical machine and a manufacturing method for a high temperature superconducting film thereof. The superconducting rotating electrical machine includes a stator, and a rotor rotatable with respect to the stator, the rotor having a rotary shaft and a rotor winding. Here, the rotor winding includes tubes disposed on a circumference of the rotary shaft and each forming a passage for a cooling fluid therein, superconducting wires accommodated within the tubes, and a cooling fluid flowing through the inside of the tubes. This configuration may allow for direct heat exchange between the superconducting wires and a refrigerant, resulting in improvement of heat exchange efficiencies of the superconducting wires.
