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.
