Kind Code:
A1
Abstract:
Provided is a motor that can switch the rotational speed of an armature by switching the energization pattern of a brush, wherein the motor can prevent the occurrence of a non-energization condition and reliably cause the armature to rotate. A coil 7 that is wound on an nth tooth section 50 is connected to a 2nth segment 14 and a (2n-1)th segment 14. An equalizing wire 52 is connected to two segments 14 on either side of four segments 14 that are sandwiched therebetween. When the tooth sections 50 around which the coils 7 that are connected to the two segments 14 short-circuited by the equalizing wire 52 are wound are respectively considered a first tooth and a second tooth, the present invention has zero, four, or eight equalizing wires 52 for which one other tooth section 50 is present between the first tooth and the second tooth.
