Abstract

The invention offers a superconducting coil, which is an oxide superconducting coilthat has the shape of a saddle formed by winding an oxide superconducting wirein the shape of a racetrack and that has a curved portionand a linear portionconnected to the curved portion. At least in the central portion of the linear portion, an upper endis positioned at the inner-circumference side in comparison with a lower end. 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).
