Motor

A motor, comprising:

• a yoke having four magnetic poles;
• an armature core, having a rotary shaft rotatably provided radially inside the yoke, six teeth attached to the rotary shaft and extending radially outward, and six slots formed between each of the teeth adjacent in a circumferential direction;
• a coil wound around each of the teeth;
• a commutator provided adjacent to the armature core on the rotary shaft, on which twelve segments are disposed in the circumferential direction;
• and
• a plurality of brushes supplying power to the coil via each of the segments, wherein
• when the teeth are sequentially numbered from 1 to 6 in the circumferential direction and the segments are sequentially numbered from 1 to 12 in the circumferential direction,
• a winding start terminal of the coil is connected to the first segment, and the coil is
• pulled around in one direction in a rotational direction of the rotary shaft from the first segment and wound around the fifth tooth in a forward direction,
• pulled around in the one direction from the fifth tooth and wound around the second tooth in the forward direction,
• pulled around in the one direction from the second tooth and connected to the twelfth segment,
• pulled around in the one direction from the twelfth segment and connected to the sixth segment,
• pulled around in the one direction from the sixth segment and wound around the sixth tooth in a reverse direction opposite the forward direction,
• pulled around in the one direction from the sixth tooth and wound around the third tooth in the reverse direction,
• pulled around in the one direction from the third tooth and connected to the eleventh segment,
• pulled around in the one direction from the eleventh segment and connected to the fifth segment,
• pulled around in the one direction from the fifth segment and wound around the first tooth in the forward direction,
• pulled around in the one direction from the first tooth and wound around the fourth tooth in the forward direction,
