  • Patent number: 6548933
    Abstract: A linear shape straight angle line is transformed to form U-shape configuration in advance and by sandwiching a stator tooth portion to adjacent slots linear shape two sides are inserted and using a thin plate rod shape chip between both ends of U-shape side of the above stated coil is connected and then the coil is formed to have one winding close circuit. The plural coils are inserted and as stated in above between the both ends of an anti-U-shape side is connected, and a stator coil for forming a predetermined winding turn number is obtained. When an end face of the anti-U-shape side and the thin plate shape chip are overlapped and connected, a plate thickness of a portion in which they are overlapped is reduced by half respectively, and when they are overlapped, it becomes the plate thickness which corresponds to a plate thickness of the above stated straight angle line coil. A length of a coil end portion can be shortened widely.
