Motor
According to the present invention, a coil is continuously wound in a single pass around each of a series of teeth, and connected to each segment.
1. 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,
pulled around in the one direction from the fourth tooth and connected to the fourth segment,
pulled around in the one direction from the fourth segment and connected to the tenth segment,
pulled around in the one direction from the tenth segment and wound around the second tooth in the reverse direction,
pulled around in the one direction from the second tooth and wound around the fifth tooth in the reverse direction,
pulled around in the one direction from the fifth tooth and connected to the third segment,
pulled around in the one direction from the third segment and connected to the ninth segment,
pulled around in the one direction from the ninth segment and wound around the third tooth in the forward direction,
pulled around in the one direction from the third tooth and wound around the sixth tooth in the forward direction,
pulled around in the one direction from the sixth tooth and connected to the eighth segment,
pulled around in the one direction from the eighth segment and connected to the second segment,
pulled around in the one direction from the second segment and wound around the fourth tooth in the reverse direction,
pulled around in the one direction from the fourth tooth and wound around the first tooth in the reverse direction,
pulled around in the one direction from the first tooth and connected to the seventh segment, and
pulled around in the one direction from the seventh segment and connected to the first segment.
