Abstract
An assembled commutator has a thermoplastics base supporting segments. A ring 15 of high temperature, non-softening material, such as phenolic, fits on a shelf on the base beneath tangs which are for hot connection, particularly forging, to an armature wire. The ring is held in place by fingers on the tangs.
