  • Patent number: 9065306
    Abstract: The invention offers a superconducting coil, which is an oxide superconducting coil 10 that has the shape of a saddle formed by winding an oxide superconducting wire 11 in the shape of a racetrack and that has a curved portion 10b and a linear portion 10a connected to the curved portion 10b. At least in the central portion of the linear portion 10a, an upper end 10d is positioned at the inner-circumference side in comparison with a lower end 10e. Having the foregoing configuration, the superconducting coil formed of an oxide super-conducting wire can suppress the reduction in its electrical property caused by the lines of magnetic flux when used in a rotating machine such as a motor. The invention also offers a superconducting-coil assembly formed by using the foregoing superconducting coils and a rotating machine incorporating the foregoing superconducting coil (superconducting-coil assembly).
