Abstract

DC60 (04/03/42) reveals the method of winding an overlapping coil (20a) on the stator of the core of an electric motor or similar. First, the first coil is wound around the stator core (14). The second coil (20) is wound so that it overlaps the first coil (20a) in the radial direction. The coil is formed over a wider range than is covered by a given number of teeth (12) of the stator core (14). In this way, a large amount of wire is formed into pieces. The final coil (20a) is pushed toward the center of the stator core (14) by a winding pusher mechanism (24). This is done to prevent the coil (20) from sliding contact with the teeth (12). Electrical insulation is maintained. Furthermore, the area factor can be improved as well. The method of winding an overlapping coil is revealed.
