Abstract

PURPOSE:To stabilize junction work by laser welding for improving reliability by exfoliating in advance an insulating coating of either junction part of the inner and outer strands, when joining the ends of the coil units consisting of the double cylinders. CONSTITUTION:A coil unit consisting of the double cylinders is formed by doubly winding around a sheet-shaped strand in a spiral form. And when both ends of coil unit are joined to form a closed loop, an insulating coating N either of the closed loop forming opposing parts 14 and 15 of the inner and outer strands is stripped to form an insulating coating stripped part 16. And said part is irradiated by laser to perform laser welding. Thereby the distance of the junction parts is shortened thus to improve reliability.
