Abstract:
1. A motor comprising: a stator, which has a plurality of magnetic poles arranged along the circumferential direction of the stator; an armature rotatable relative to the stator, the armature including: an anode supply brush and a cathode supply brush, wherein the supply brushes slide against the commutator, and wherein the supply brushes are arranged at a predetermined angular interval about the axis of the commutator, wherein each short-circuit member has a base portion and a plurality of arms radially extending from the base portion, wherein each of the arms of each short-circuit member corresponds to one of the predetermined number of the segments to be short-circuited and has a segment connection portion to which the corresponding segment is connected, wherein the base portions are laminated to have a multi-layer structure along the axial direction of the commutator such that the short-circuit members form a laminated body, wherein the arms are formed such that the segment connection portions are located in the same position with respect to the axial direction of the laminated body, and wherein the arms include specific arms each of which is provided with a connector at a distal end, wherein each connector is located radially outwards with respect to the segment connection portion and is directly connected to an end of one of the coils.
