Abstract: According to one embodiment, the present invention provides a rotor assembly. The exemplary rotor assembly includes a plurality of rotor laminations, which cooperate to form a rotor core, capped at each end by end members. Extending through the rotor core and the end members, a plurality of rotor channels is configured to receive electrically conductive members therethrough. Each of the electrically conductive members has external portions, which extend beyond the rotor channel, and an interior portion that is housed within the rotor channel. By flexing the external portions, a compression force that secures the laminations and the end members with respect to one another may be provided. Advantageously, the external portions may be fused to one another and/or to the end members. As one example, the external portions may be fused through the introduction of a molten metal into the end member.

Abstract: A system for cooling a superconductor device includes a cryocooler located in a stationary reference frame and a closed circulation system external to the cryocooler.

Abstract: A superconducting electromechanical rotating (SER) device, such as a synchronous AC motor, includes a superconducting field winding and a one-layer stator winding that may be water-cooled. The stator winding is potted to a support such as the inner radial surface of a support structure and, accordingly, lacks hangers or other mechanical fasteners that otherwise would complicate stator assembly and require the provision of an unnecessarily large gap between adjacent stator coil sections. The one-layer winding topology, resulting in the number of coils being equal to half the number of slots or other mounting locations on the support structure, allows one to minimize or eliminate the gap between the inner radial ends of adjacent straight sections of the stator coilswhile maintaining the gap between the coil knuckles equal to at least the coil width, providing sufficient room for electrical and cooling element configurations and connections.
