Abstract
Superconducting electrical machines, for example motors or generators, especially high-temperature superconducting machines, include a rotor equipped with superconductors, especially high-temperature superconductors. They further include a rotor cryostat, a rotor shaft and a cryostatic link including a cryostatic conductor between the cryostat and a frigorific apparatus, and a non-superconducting stator. The machines are adapted to be resistant to shocks as required for navy ships. The stator, the rotor and the cryostat are motion-decoupled from an outer machine housing and the rotor shaft by elastic elements. In one embodiment, the machine housing is configured as a thruster housing and is elastically linked with the stern of the ship.
