1. A dynamo-electric machine comprising:
- a commutator having commutator segments secured to a shaft;
an armature having a winding composed of a wire or wires wound by a lap winding method through slots extending in the axial direction formed on the outer circumferential surface of a core secured to said shaft, with said wire or wires being directly electrically attached to a portion of said commutator segments;
and an equalizer disposed adjacent to said commutator in the direction of the axis of said commutator having terminals stacked in the axial direction which are directly electrically attached to a portion of said commutator segments separate from said wires, and which electrically connect commutator segments which having substantially the same electric potential.

Abstract
A dynamo-electric machine comprises an armature having a winding composed of a wire or wires wound by a lap winding method through slots extending in the axial direction formed on the outer circumferential surface of a core secured to a shaft, a commutator having commutator segments secured to the shaft, and an equalize disposed adjacent to the commutator in the direction of the axis of the commutator having terminals stacked in the axial direction which electrically connect commutator segments which should have the same electric potential.

15. A method of manufacture for a dynamo-electric machine comprising:
-
an armature having a winding composed of a wire or wires wound by a lap winding method through slots extending in the axial direction formed on the outer circumferential surface of a core secured to a shaft; a commutator having commutator segments secured to said shaft; and an equalizer disposed adjacent to said commutator in the direction of the axis of said commutator having terminals which electrically connect commutator segments which have substantially the same electric potential; said method of manufacture comprising the steps of; contacting said wire to a surface of hooks on said commutator segments; contacting end portions of said terminals to another surface of said hooks; and electrically connecting said wire and end portions of said terminals to said hooks simultaneously by fusing.
