PURPOSE:To prevent the deterioration of characteristics and the breaking of a wire with winding distortion of a starand reduced by realizing the split structure obtained by stacking a composite superconductor material with rectangular section from the center line of a superconductive coil toward the radius direction. CONSTITUTION:To wind composite superconductor material 1 whose section is rectangular with superconductive strand 3 buried in sub-straight 2 [width (t) < width (w)] in an edge-wise winding method making (t) in parallel to the center line of the coil, three spools 9 of three bodies 8 obtained by dividing strand 1 into three in the radius direction and spool 10 of insulating tape 4 are empolyed and the contact surface of material 8 is brazed to bobbin 12 fixed to rotary disc 11 over a winding of one layer of tape 4 around the inmost part and three layers of materials 8 at its outside. In comparison with a flat-wise winding method making W of strand 1 in parallel to the coil center line, a loss of an overcurrent is small, its cooling area is wide, and the distortion of the strand in case of the edge-wise winding method can be reuced remarkably. |
