PURPOSE:To prevent the temperature rise of a slip ring of a slide for connecting an exciting power source and to eliminate frost of a superconductive rotary electric machine by arranging gas passages of parallel routes in the intermediate couping shaft, on which the slip ring is mounted. CONSTITUTION:An axial cooling hole 39 passed axially in an intermediate coupling shaft 32, on which a slip ring 20 is mounted, a circumferential cooling groove 40 formed on the outer periphery and an axial cooling groove 41 communicating with the groove 40 are arranged. Further, a radial cooling hole 38 for coupling them is formed, the shaft 32 is operated as a recovery pipe of a recovery gas passage in a structure for gradually cooling the slip ring 20 from the bore, thereby preventing the temperature rise. |
