Abstract: A trace is disclosed formed of superconductive material. The trace is formed in an elongate, non-linear trace pattern characterized by (i) a trace pattern thickness, (ii) a trace pattern width greater than the trace pattern thickness, (iii) a trace pattern length greater than the trace pattern width, and (iv) a trace pattern axis extending along the trace length and defining an instantaneous alignment tangential to the trace pattern axis. The trace pattern is further characterized by (i) a envelope within which the trace pattern lies and (ii) an envelope axis defining an alignment of the envelope. The trace comprises at least two electrically connected sections, where each section includes (i) a first turn in which the trace pattern instantaneous alignment rotates about 180 degrees in a first direction around a first turn focus, and (ii) a second turn in which the trace pattern instantaneous alignment rotates about 180 degrees in a second direction, opposite the first direction, about a second turn focus.

Abstract: A motor is provided. The motor includes a winding support element defining an interior, a rotor having a shaft mounted inside the interior, the shaft defining a central axis, a superconducting wire wound around the winding support element in a winding pattern, where the winding pattern includes a plurality of turns around the winding support element. The winding pattern includes for a first portion of each turn proximate to the rotor, the wiring pattern curves with respect to a toroidal angle about the central axis, and for a second portion of each turn distant from the rotor, the wiring pattern curves with respect to a toroidal angle about the central axis. Cooper pairs travelling through the wire accelerate with respect to the toroidal angle in the first portion, and decelerate with respect to the toroidal angle in the second portion.
