PURPOSE:To avoid a thermal influence due to soldering or welding by interposing the end of a coil wire between a commutator segment and a coil supporting base, thereby mechanically fixing the coil and electrically connecting to the segment. CONSTITUTION:The semiconductor segments 2 formed on the outer peripheral surface of a commutator base 1 are exposed on the end of a commutator base 1. A commutator 3 is press-fitted to a rotor shaft 4, the ends 7 of the coil 6 wound on a coil supporting base is interposed between the segments 2 and the base 5, and the ends 7 of the coil and the segments 2 are electrically coupled by pressure contacting. |
