Abstract
An assembled commutator comprises a base carrying segments. Each segment 16 has a connector portion with a wall portion having an aperture to locate the connector portion about a projection on a collar formed on the base, to locate the segment. The connector portions each have a U-shaped portion having a radially inner arm which rests on the collar and is wider than the radially outer arm, to form wings which can be used when hot forging a tang to an armature coil wire, with a first electrode bearing down on the arm and a second electrode bearing down on the wings.
