PURPOSE:To prevent the damage of the insulating coating or the like of a coil strand by bonding inner kand outer coil strands not by welding but by soldering or brazing. CONSTITUTION:Inner and outer cylindrical coils are engaged to radially superposing coil strands 1, and coupling rings 3 are superposed thereon so that coupling materials 6 correspond onto the strands 1 radially superposed. Electrodes are connected to the left and right ends of inner and outer ring frames 4, 5, and energized therebetween. A brazing or soldering material which is covered by heating by energization on a conductor is then molten, and the strands 1 to be radially superposed by the brazing or soldering material are simply bonded by the materials 6. |
