대표청구항 ▼

1. A superconducting coil assembly comprising: a plurality of superconducting windings disposed along a longitudinal axis of the coil assembly, each superconducting winding being non-circular in shape and formed of a strain-sensitive material; internal coil support members positioned between adjacent ones of the plurality of superconducting windings and configured to reduce internal strain generated in the windings; the internal coil support members being positioned between adjacent ones of the plurality of superconducting windings and on a wide surface of the superconducting windings, thereby forming a laminated stack alternating between the internal support members and adjacent ones of the superconducting windings, at least some of the internal coil support members including a composite material; and epoxy for impregnating the laminated stack. 2. The superconducting coil assembly of claim 1 wherein the non-circular shape is a racetrack shape defining a pair of opposing arcuate end sections and a pair of opposing substantially straight side sections. 3. The superconducting coil assembly of claim 1 further comprising: at least one fastener; and a rotor body; the rotor body being cylindrical in shape and having an outer surface, the fastener being passed through the superconducting coil assembly at a point in an annular opening defined by the superconducting windings and fastened into the rotor body outer surface, thereby mounting the coil assembly to the rotor body and tying the internal coil support members together into a unitary whole. 4. The superconducting coil assembly of claim 3 wherein the fastener is a bolt. 5. The superconducting coil assembly of claim 1 wherein the internal coil support members further comprise openings to allow for electrical connections between adjacent superconducting windings separated by the internal coil support member. 6. The superconducting coil assembly of claim 1 wherein the at least one internal coil support is stainless steel. 7. The superconducting coil assembly of claim 1 wherein the strain-sensitive material is a superconducting ceramic oxide. 8. The superconducting coil assembly of claim 7 wherein the superconducting ceramic oxide is a high temperature superconducting ceramic oxide. 9. The superconducting coil assembly of claim 8 wherein the high temperature superconducting ceramic oxide is BSCCO 2223. 10. The superconducting coil assembly of claim 1 wherein the superconducting windings are single pancake coils. 11. The superconducting coil assembly of claim 1 wherein the superconducting windings are double pancake coils. 12. The superconducting coil assembly of claim 1 wherein the internal coil support members are 0.040 inches thick. 13. The superconducting coil assembly of claim 1 wherein the at least some of the internal coil support members are formed of a fiberglass composite. 14. The superconducting coil assembly of claim 1 wherein the at least some of the internal coil support members include a thermally conductive coating. 15. The superconducting coil assembly of claim 1 further comprising an end cap positioned at an end region of the plurality of superconducting windings.
