Abstract
A commutator has a plurality of commutator segments fixed to an insulating support member. The commutator segments are formed by cold or hot forming a copper billet cut from a length of copper wire. Each billet has a volume approximately equal to the volume of one commutator segment. Each commutator segment has a main body and an anchor integrally formed with the main body. The commutator segments are spaced about a circle and then an insulating support member is molded to the commutator segments to fix the commutator segments to the support member.
