ABSTRACT:
A direct current motor with brushes in which an armature is provided with a rotating shaft that is supported by a yoke housing, an armature core that is fitted and fixed to a rotating shaft from the outer side, and a commutator that is provided on the rotating shaft adjacent to the armature core with nine segments arranged in the circumferential direction. The armature core has nine teeth that extend in the radial direction in a radial pattern and nine slots that are formed between the teeth and extend in the axial direction, the segments having the same polarity are connected with short-circuiting members, and a pair of brushes that make sliding contact with the segments is disposed so as to be mutually point symmetric centered on the rotating shaft. According to the preset invention, it is possible to effectively achieve flattening of the direct current motor.
