Abstract

1487923 Commutators LUCAS ELECTRICAL Ltd 2 Jan 1975 [16 Feb 1974] 7180/74 Heading H2A [Also in Division B3] A planar commutator comprises a plurality of segments 12 and a moulded synthetic resin support body 11, each segment 12 being keyed into the body 11 at the radially outer region by means of a pair of rearwardly extending circumferentially divergent integral projections 17a, and at the radially inner region by means of a rearwardly extending lug 18a having an undercut surface 22. The projections 17a and the lug 18a define walls of a channel 16 formed in the rear face of each segment 12. Each segment has a radial slot (not shown) for receiving a connecting wire. The segments are formed by division from an annular grooved conductive body, to which synthetic resin has been moulded (Division B3).
