PURPOSE:To improve the superconductive characteristic of a superconductive rotor and to increase the output per unit area by axially dividing a rotor coil into a plurlity, arranging small pieces at the distance on the divided surfaces, and providing a coolant medium flowing passage between the divided surfaces. CONSTITUTION:Small pieces 16 are interposed between 3 circular coils in a rotor coil 15, a duct 17 for flowing coolant medium is formed between coil layers, and pole filler 18 is mounted in the inner ring. A spacer 22 which becomes the same size as the size of the upper surface of the coil 15 is mounted in space between the fillers 18 on the upper surface of the uppermost layer of the coil 15 to form an inner peripheral side passage 23. Further, the coil 15 and the filler 18 are held by centrifugal force by a bind 24 on the top, an outer peripheral side passage 25 is formed between the bind 24 and the outer peripheral wall 7, thereby flowing the cooling medium. In this manner, the cooling performance of the coil 15 can be improved. |
