Abstract
PURPOSE:To simplify structure and facilitate the manufacture a motor by a method wherein a spark quenching element is attached to the rear surface of a commutator segment, and the segment together with the commutator proper are molded with an insulating heat-melting material to facilitate the fixation of the spark quenching element. CONSTITUTION:A spark quenching element 16 such as varister or capacitor is attached onto the surface of each of the commutator segments 10a<-1>-10a<-3> between the segments. The spark quenching element 16 together with the commutator proper 10B are molded with an insulating heat-melting material so that they are completely buried in the mold. By so doing, it is simplified to fix the spark quenching element 16 and carry out such work, while the fixation of the spark quenching element is made solidified. Dampproofness can also be improved.
