A superconductor coating inclusive, tape-like electrical conductor and
windings using such conductor for magnets and electrical machines, etc.
The described windings are suited for inclusion of successor
superconductor materials such as yttrium barium copper oxide wherein
magnetic flux related losses can potentially be excessive and preclude
successful machine operation. Winding orientation and configuration of
the conductor in an alternating current machine for lower losses are
disclosed along with methods and apparatus for achieving the desired
windings. Windings intended for differing locations within a machine of
this type are made possible by the invention. Equations relating to
magnetic losses incurred in such windings are also disclosed.

We claim:
1. A method of fabricating a high temperature superconductor film layer inclusive multiple turn, multiple coil electrical winding, said method comprising the steps of: dividing a
planar sheet of high temperature superconductor film coated electrical conductor material into segregated lengths of tape conductor having conductor interconnecting regions located at one end of each tape conductor, said conductor dividing step forming
an extended connected meander-like pattern of tape conductors in said sheet of high temperature superconductor film coated electrical conductor material; and forming said divided pattern tape conductors into axially segregated multiple turned continuous
electrical winding coils wherein each said conductor interconnecting region comprising a portion of said coil includes a length of said high temperature superconductor coated tape conductor.
2. The method of fabricating a high temperature superconductor film layer inclusive multiple . . . . More |
