Abstract
The commutator comprises a commutator base and a plurality of commutator segments. The base is in two parts. One part is a pre-formed base part and the other part is moulded to the base part after the segments have been located on the base part to firmly secure the segments thereto. The commutator is of the barrel-type and the base part is tubular and has castellated ends. The segments have apertured lugs which engage with the castellated ends of the base part and extend inside opposite ends of the base part to locate the segments relative to the base part. The other part of the base forms a sleeve inside the pre-formed base part and firmly secures the lugs and hence the segments to the pre-formed base part.
