ABSTRACT:
A rotary electric machine and a commutator for the rotary electric machine are disclosed wherein the commutator includes an insulating member carrying thereon a plurality of commutator segments each having a brush contact surface. Each commutator segment has an embedded portion formed with a tab tail, molded to the insulating member, and has a riser portion radially extending outward from the brush contact surface to be electrically connected to armature coils. The insulating member has a large diameter portion and an increased wall thickness portion, axially extending from the large diameter portion in a direction away from the riser portion, with a sum of axial wall thicknesses of the increased wall thickness portion and the large diameter portion lying in a value two times an axial wall thickness of the riser portion. The increased wall thickness portion is formed in a tapered shape.
