Title:
Superconductivity rotating machine
Document Type and Number:
Japanese Patent JP6024539
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a superconducting rotary machine capable of suppressing operation cost and preventing an increase in starting torque.SOLUTION: A superconducting rotary machine includes: a rotor 20 which is rotated inside of a stator 10 while being cooled together with the stator 10; a container 30 in which the stator 10 and the rotor 20 are housed together with a liquefied coolant R; a rotor rotary shaft 21 fixed to the rotor 20; and bearings 50, 51 by which the rotor rotary shaft 21 is rotatably supported outside of the container 30. The container 30 is equipped with cylindrical parts 32, 33 into which the rotor rotary shaft 21 is inserted. The rotor rotary shaft 21 includes: a first solid shaft part 1 inserted into the rotor 20; and a second cylindrical-shape shaft part 2 which is inserted into the cylindrical parts 32, 33 and forms a vacuum space 4 inside.
