Abstract
An assembled commutator comprises a cylindrical base and a plurality of segments glued on the base. To secure the segments on the base a loop, formed by stamping out a tang, is urged over a boss on the end of the base. A tongue is inserted in a recess at the other end of the base, as is known in the art. The loop pulls the segment down onto the base and also prevents circumferential movement.
