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.

Abstract: Disclosed is a ship propulsion system comprising a synchronous machine (6) with an especially superconducting rotor winding that is to be subjected to intense cooling and a normally conducting stator winding (11) which is to be cooled. The stator winding (11) is disposed at least in part inside a support structure (14) encompassing a hollow cylindrical magnetically soft outer body (13) and web-type support teeth (21i) that extend in an axial and radial direction. A hollow cylindrical part (15a) of an exterior housing (15) encloses the outer body (13). In order to cool at least some areas of said housing part (15a), the stator winding (11) is thermally coupled to water as a cooling medium (K) via the support structure (14) and the housing part (15a).
