Abstract

1305415 Moulding commutators SOC INDUSTRIELLE DE TRAVAUX ELECTRO-MECANIQUES 4 May 1970 [2 May 1969] 21420/70 Heading B5A [Also in Division B3] A mould 4 has guideways 3 separated by ridges 5 and into which are fitted commutator segments 1, the latter being formed with terminal loops 7 engaging a projecting ring 8. The segments abut a reinforcement ring 6, and the height of the ridges 5 is the minimum consistent with accurate positioning of the segments. Preferably the exterior surface of the mould 4 is conical for centering in a holder. A mandrel may be inserted in the mould if the commutator is formed separately, bearings being moulded inside the commutator, or the commutator may be moulded directly on to a shaft. Alternatively the mould may comprise a plurality of steel inserts 16 separated by strips 15, which position the segments. The inserts may be changed to accommodate different commutators.
