Abstract
A method of preliminarily bending ends of windings in an armature assembly having at least two layers provides an armature assembly for a dynamoelectric machine that does not require a layer of insulation between terminal portions of conductive windings between the armature lamination assembly and the commutator. The preliminary operations may also include trimming of the free ends of the terminal portions of windings, so that a substantially, fully machined commutator assembly may be used, providing improved electrical contact during a resistance welding or brazing step for affixing the ends of the windings to respective commutator segments. The commutator segments may be manufactured without riser portions, resulting in a less costly assembly which is less susceptible to damage during handling during assembly.
