Abstract:
The present invention relates to a synchronous superconductive rotary machine with a superconductive rotor, a wind turbine, an assembly method and a repair method there- of. The rotor comprises a back iron connected to a thermally insulating support struc- ture which is further connected to a base element. A coupling element is arranged on a peripheral surface of the base element for coupling to a matching coupling element located on a peripheral surface of a pole unit. The pole unit comprises a core element on which the coupling element is located and superconductive coils are wound on the core element. The pole unit is slid into position in an axial direction and fixed relative to the back iron by using fastening means. The base element, support structure and pole unit are wrapped in a thermal insulating laminate. This provides a simple and easy assembly and repair process that does require the rotor to be separated from the stator in order to replace a pole unit.

Abstract:
A superconducting electrical generator or motor having a plurality of cryostats is described. The cryostats contain coolant and a first cryostat encloses at least one of a plurality of superconducting coils. A first coil is in superconducting electrical communication with a second coil contained in a second cryostat through a superconducting conduction cooling cable enclosing a conductor. The first cryostat and the second cryostat may be in fluid communication through at least one cryogen channel within the at least one superconducting conduction cooling cable. In other embodiments, none of the plurality of cryostats may be in fluid communication and the cable may be cooled by conduction along the conductor from the first or second cryostat, or from both. The conductor may have different segments at temperatures equal to or above the temperature of the coolant and the superconducting conduction cooling cables may be connected through quick connect fittings.
Abstract:
A cryostat cartridge is disclosed. The cryostat cartridge may include a cryostat having a cryogen inlet, a cryogen outlet, and a superconductor material inside the cryostat configured to be cooled by a cryogen entering the cryostat through the cryogen inlet and exiting the cryostat through the cryogen outlet. The cryogen inlet is configured to be detachable from a cryogen source. The cryostat cartridge may be inserted into an activation module for activating the superconductor material and may also be inserted into a superconductor device.

Abstract:
The present invention relates to a coil support member (1) and a method of manufacturing the same in which a thermosetting or thermoplastic material is introduced into a mould cavity and hardened. One or more components (12, 14) are positioned within the mould cavity during the manufacturing process before the thermosetting or thermoplastic material is introduced. These components are then embedded in the thermosetting or thermoplastic material and form an integral part of the coil support member (1). One or more functional filler materials are added to the thermosetting or thermoplastic material to improve the thermal matching between the integral components and the thermosetting or thermoplastic material.
