摘要： A stator has a stator core composed of teeth and slots. Segment coils are inserted into the corresponding slots. The segment coil projecting from the slot has an exposed conductor part and a covered conductor part covered with an electrical insulation film. The exposed conductor part is arranged at the distal end side from the covered conductor part of the segment coil. The segment coils are connected together through the exposed conductor parts thereof projecting from the slots. The exposed conductor part has a thickness T2 thinner than a thickness T1 of the covered conductor part. A step part is formed at a position of the stator core side, adjacent to the exposed conductor part of the segment coil. The step part and the covered conductor part are covered with the electrical insulation film continuously from the stator core side of the covered conductor part.

摘要： A conveyer equipped with rotating discs rotatable around axes thereof relative to a mounting base. Each of the rotating discs has grooves in which rectangular wires are receivable. When an upstream and a downstream one of the rotating disc are arranged in a given angular relation to each other, one of the grooves of the upstream rotating disc is aligned with that of the downstream rotating disc to pass the rectangular wire from the upstream rotating disc to the downstream rotating disc. Upon such passing of the rectangular wire, the grooves of the upstream and downstream rotating discs hold or clamp all side surfaces of the rectangular wire, thereby ensuring the stability in retaining the rectangular wire when passed from one to another of the rotating discs, which enables the conveyer to carry the rectangular wires at high speeds.

摘要： A method of removing an insulating coating layer of coil wiring includes: a fragmentation step in which a line-shaped region of the insulating coating layer, which separates a removal-planned portion and a remain-planned portion of the insulating coating layer, is removed; a laser irradiation step in which laser light which transmits through the insulating coating layer but which is absorbed by a coil wiring is irradiated from a side of an outer surface of the removal-planned portion toward a boundary of the coil wiring with the insulating coating layer, to carbonize a boundary portion between the insulating coating layer and the coil wiring of the removal-planned portion by generation of heat of the coil wiring; and a coating turn-over step in which air is blown onto the removal-planned portion to turn over and blow off the removal-planned portion.
