Abstract

PURPOSE: To prevent disconnection and commutation failure by parallelly overlapping the conductor winding start end and tail end of the cylindrical coil tap section, electrically connecting them each other, bending and overlapping them on th surface of the cylindrical coil in the conductor winding direction, and positioning them on the external surface of the cylindrical coil.
CONSTITUTION: The conductor 1 is obliquely wound and repeatedly bent obliquely to form the cylindrical coil 2. The winding start end 3 and the winding tail end 4 are parallelly overlapped. For example, these sections are overlapped on the external surface of the cylindrical coil 2 along with the winding direction of the conductor 1 and electrically connected by solder. Then, as shown in Fig. (a), the cylindrical core 10 is inserted into the inner part of the cylindrical coil 2 and the coil forming mold 11 is pressure-contacted from both sides. As shown in Fig. (b), the solder sinks into the inner part of the cylindrical coil 2 from its external surface and a perfect cylinder is formed. The commutator stand 12 is inserted on the upper end of the external surface of the cylindrical surface 2. A five-divided commutator is arranged on it and electrically connected to the energized section 13.
