Abstract:
In a stator of a rotating electric machine in which a stator coil is mounted on plural slots of a stator iron core, comprisinga linear-shaped stator coil that has been preformed to a U-shape configuration with straight sides and a bent portion, a tooth portion of said stator is sandwiched between said straight sides, after said straight sides are inserted to adjacent slots, and a thin plate rod-shaped chip is connected between both free ends of said linear-shaped stator coil to form a winding close circuit; said linear-shaped stator coil having a predetermined turn number; said free ends of said straight side and said thin plate rod shape chip are overlappingly connected; a thickness in a portion in which said free ends and said chip are overlapped is reduced by half, respectively, so as to have a plate thickness which corresponds to a plate thickness of said linear-shaped stator coil; in a face in which said plate thickness is reduced by half, in one side of one end of said linear-shaped stator coil, a plate thickness directed toward an inner diameter of said stator is reduced by half, in another side of said one end of said linear-shaped stator coil, a plate thickness directed toward an outer diameter of said stator is reduced by half; said thin plate rod shape chip having a face with a plate thickness reduced by half; said straight sides of said U-shape configuration coil sandwich said thin plate rod shape chip.
