ABSTRACT:
An armature core subassembly and a commutator to be assembled thereon are each centered on a common axis and rotated relative to one another until a desired angular alignment is obtained between a side edge of a commutator bar and the armature core slots. This orientation is maintained while the commutator is advanced to and pressed onto the armature shaft. A commutator placing machine is described in which a tang-oriented commutator is loaded into the nosepiece of a ram assembly and the ram assembly is rotated by a stepper motor until an edge of a commutator bar is detected at a predetermined location by an optical edge detector. Prior machines for tang-orientation and orientation by insulating gaps between commutator bars are also described.
