Abstract

A face commutator for a dynamo electric machine comprising a moulded synthetic resin body arranged to be secured to a dynamo electric machine rotor shaft for rotation therewith and a plurality of conductive segments carried by the body. The segments are disposed on the body in a circle having its centre on the rotational axis of the body, and each segment extends radially with respect to the axis of rotation. The front faces of the segments are generally co-planar and their rear faces are presented to the body, each segment being keyed into the moulded body at both its radially innermost and its radially outermost end of its rear face. Each segment is keyed to the body at its radially outermost end of its rear face by means of a pair of rearwardly extending, divergent integral projections. The specification also discloses and claims a method of manufacturing the face commutator.
