SADDLE SHAPED COIL WINDING USING SUPERCONDUCTORS AND METHOD OF MAKING SAID COIL WINDING Russian patent published in 2009 - IPC H01F6/06 H01F41/04 

FIELD: physics.

SUBSTANCE: proposed saddle shaped coil winding (3) is made from a flat shape of a race track type coil on a pipe-like lateral surface (Mf) such that, it contains winding sections (3a) axially passing on the lateral side and winding sections (3b, 3c), passing between them on frontal sides, which form end windings. Separate turns (W_i) of the coil winding must be made from at least one tape of a superconductor (5), particularly with superconducting material with high critical temperature T_c, whose narrow side (5a) faces the pipe-like lateral surface (Mf). To prevent inadmissible mechanical loads on the conductor when forming the winding, turns (W_i) in the saddle shape must have perimetre (U) respectively, which remains virtually unchanged compared to that in a flat coil.

EFFECT: efficient use of superconducting material from ready tape-like conductors with compact arrangement of windings; small diametre can be achieved of the area forming the pipe-like lateral surface.
