Abstract
PURPOSE:To improve shielding performance and to reduce Joule hear, by using a superconductor to the conduction section of a low temperature damper. CONSTITUTION:A low temperature damper 51 of the rotor of a superconductive rotary electric machine is equipped with a superconductor 51a fixed to the grooves of a cylindrical support 51b. This superconductor 51a is provided axially and circumferentially to form a squirrel-cage electric circuit. In order to play a role as a radiating shield, the low temperature damper 51 is kept to 80-100 deg.K with a low temperature gas going through a cooling hole 51c. This superconductor 51a is formed in e.g. an oxide superconductor Y-Ba-Cu-O. If the variable field is applied to the low temperature damper 51, the current to deny the variable field will flow through the superconductor 51a, so that a remarkable shielding effect can be taken.
