PURPOSE:To improve reliability, by a method wherein the teeth of a slot core are extended in accordance with the length of the coil end of a field coil while corner blocks are fitted into the corners of the coils. CONSTITUTION:The cold rotor 1 of a superconductive rotor is constituted of three layers consisting of an outside shaft 21, a cold damper 22, fitted to the outside of the outside shaft 21 and made of good conductive material, and the damper support 23 of high strength non-magnetic material, which is provided at the outside of the normal-temperature damper 22. The outside shaft 21 is provided with a radiation shield 2 at the inside thereof through a vacuum part 11. A coil supporting tube 4 is provided with a plurality of slots and superconductive field coils 3 are received therein. Extensions 31' of teeth of slot teeth 31 between coils are provided from the end 30 of the core of the pole of said supporting tube 4 while corner blocks 32 are fitted forcibly into the ends of the coils. Radial blocks 16 are inserted between circumferential coils. According to this constitution, the coil may be pushed perfectly and quench, generated by heat generation, may be prevented. |
