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.

Superconducting rotating electrical machine and manufacturing method for high temperature superconducting film thereof

Disclosed herein is a superconducting field coil of a homopolar type superconducting synchronous machine. The superconducting synchronous machine includes a superconducting field coil which comprises a single or double pancake coil formed by winding a superconducting wire, a core-type rotor which is made of a magnetic material, and an armature winding excited to three phases on a surface of a core of a stator. The field coil of the homopolar type superconducting synchronous machine is not rotated when the machine is in operation. Thus, there is no part for coupling the rotating field coil to a stationary cryo-cooler for cooling a refrigerant, so that the structure is simple, reliability is high, and various cooling methods are available.
