Abstract

A superconducting machine is disclosed, in particular for use as a generator in a stand-alone power system. In at least one embodiment, the superconducting machine includes a stator and a rotor capable of rotating with respect to the stator. At least one superconducting coil for generating at least two magnetic poles is provided on at least one component part, in particular the rotor, which superconducting coil is cooled via a cooling device; and at least two parallel winding elements are provided on the respective other component part, in particular the stator, in the armature winding for each phase, which winding elements can be connected either in series or in parallel via at least one switching device.
