摘要
A superconducting rotating machine comprises a cylindrical frame, a stator installed integrally around an inner periphery of the cylindrical frame and a rotor arranged concentrically and rotatably within the stator in a juxtaposed spaced relationship to the inner surfaces of the stator and with a cylindrical clearance between the inner periphery of the stator and the outer periphery of the rotor. The stator coil includes a primary coil having extra fine Cu filaments and a secondary coil having extra fine filaments made of a superconducting alloy containing Cu, Nb. sub.3 Sn, V.sub.3 Ga, V.sub.3 Ge, Bi, Ca, CuO and Sr. The secondary coil is covered with an insulating layer. Even if a conventional rotatable cryogenic container is not provided, a strong anomalous pseudo-Josephson effect can be obtained. A superconducting generator for use in lighting equipment is also disclosed.
