Abstract
PURPOSE: To reduce the gap between a magnet and the connected parts of a commutator plate and armature coils, by making the surface of the commutator plate lower than that of each armature coil which is almost elliptically formed by winding a copper wire around an iron wire coil plate.
CONSTITUTION: An iron wire coated with an electric insulating film is wound to manufacture a slender elliptic iron wire coil plate 1. A copper wire is wound around the coil plate 1 to manufacture an elliptic armature coil. A commutator plate 3 is set in the center of a disc-shaped recess of a metal mold so that the surface of the commutator plate 3 is by 1mm lower than that of the armature coil. The armature coil and the commutator are connected to each other along the recess so that a soldered face 7 is located below the surface of the armature coil. A plurality of such armature coils are sequentially provided around the commutator plate. A synthetic resin 6 is injected into the metal mold so that the commutator plate and the armature coils are integrated with each other as a disc. A shaft 5 is provided through the center of the disc. As a result, the connected parts of the commutator plate and the armature coils are located at a small distance from a magnet 11 and the efficiency of a motor is raised.
