Title:
SUPERCONDUCTING ELECTRICAL MACHINES FOR USE IN NAVY SHIPS
Document Type and Number:
WIPO Patent Application WO2003019759
Kind Code:
A3
Abstract:
The invention relates to superconducting electrical machines, for example motors or generators, especially high-temperature superconducting machines. The inventive machines comprise a rotor equipped with superconductors, especially high-temperature superconductors, a rotor cryostat, a rotor shaft and a cryostatic link comprising a cryostatic conductor between the cryostat and a frigorific apparatus, and a non-superconducting stator. The inventive machines are adapted to be resistant to thermal shocks as required for navy ships. According to the invention, the stator (13, 29), the rotor (18, 28) and the cryostat (15) are motion-decoupled from an outer machine housing (4, 23) and the rotor shaft (12) by elastic elements (17, 25). In an embodiment of the invention, the machine housing is configured as a thruster housing and is elastically linked with the stern of the ship.
