Abstract:
Provided is a motor armature, wherein an armature-coil winding wound around a hook of a commutator segment is made so as not to break over time at the position of the hook. The motor armature comprises a commutator (20) upon which hooks (23) are arranged radially, and is configured such that the armature-coil winding (W) is connected to each of the commutator segments (22) by having the wiring (W) wound around each of the hooks (23) and having the hooks (23) bent thereafter. The motor armature also comprises a superimposing member (30) that is comprised of a ring section (31) arranged to be coaxial with the commutator (20); and sections (33) to be wound-around that are formed on the outer circumference of the ring section (31) so as to jut out radially therefrom, and configured to be superimposed with each of the hooks (23). The wiring (W) is wound around sections where the sections (33) to be wound-around of the superimposition member (30) and the hooks (23) are superimposed.
