DC COMMUTATOR MOTOR AND AUTOMOBILE INCLUDING THE SAME

A DC commutator motor includes a yoke, a field magnet, and an armature. A shaft is positioned on a central axis of the armature. A plurality of commutator segments is positioned in a circumferential direction of the shaft. A plurality of armature slots is formed on an outer periphery of an armature core. An upper coil is wound the number of turns Na through two armature slots, which are located apart from each other with the predetermined number of armature slots therebetween, at their opening sides. A lower coil is connected in parallel with the upper coil and wound the number of turns Nb through the two armature slots at their bottom sides. The number of turns Na is smaller than the number of turns Nb.
