Abstract
A face commutator for a dynamo electric machine comprises a body carrying a plurality of conductive segments. The segments are arranged in a circle with each segment extending radially. The rear face of each segment includes a channel the radially outermost wall of which is defined by a pair of rearwardly extending circumferentially divergent integral projections which key the outer end of the segment into the body. The other wall of the channel of each segment is defined by a rearwardly extending lug adjacent the radially inner end of the segment, the face of the lug presented to the pair of projections being undercut and so providing keying to the body at the radially innermost end of the segment.
