SUPERCONDUCTING ROTATING ELECTRICAL MACHINE

摘要

PURPOSE: A superconductive rotating electric machine is provided to improve the heat exchange efficiency by using a cooling fluid passing through the inside of a tube. CONSTITUTION: A rotor (120) includes a rotary shaft (121) and a rotor coil. The rotor rotates around a stator (110). A tube (141) is arranged in the circumference of the rotary shaft. A superconductive wire is placed inside the tube. A cooling fluid flows through the inside of the tube.
