Abstract: A small brush motor able to use a three-electrode varistor and able to suppress disconnection or short-circuits of crossover wires of coils, wherein each phase coil of the three-phase coil of an armature uses three risers and two salient poles, each phase coil has a zigzag part formed by alternately bending and connecting successively to the front side, back side, and back side the three salient poles in the interval from the knotting part of the first riser in the forward rotation direction to the knotting part of the second riser, a first coil part formed by winding from the knotting part of the second riser in the reverse rotation direction and wrapping at the adjoining first salient pole, and a second coil part comprised by winding from the first coil part in the forward rotation direction and wrapping at the adjoining second salient pole and connects to a knotting part of the adjoining opposite phase first riser extending from the second coil part in the forward rotation direction, the winding directions
