ABSTRACT:
An armature conductor to commutator bar connection. The bars of the commutator have radially extending slots that are defined by surfaces that taper outwardly. The ends of the armature conductors are formed to a generally wedge-shaped configuration such that the side surfaces are tapered inwardly. After the ends of the armature conductors have been formed to the tapered shape they are pushed into the slots of the commutator bars to such a depth that there is an interference fit between the side surfaces of the ends of the armature conductors and the tapered walls of the slot to lock the ends of the armature conductors to the commutator bars. After the ends of the formed armature conductors have been pushed into the slots, portions of the commutator bars are staked over into engagement with the top armature conductor end.
