Abstract

281,860. British Thomson-Houston Co., Ltd., and Henton, A. G. Nov. 19, 1926. Commutators. - An axial commutator for a dynamo-electric machine is formed by stamping the segments 1 from sheet copper, bending them to the shape shown, assembling the shaped segments in a mould and uniting them by moulded insulating material such as a synthetic resin which is subsequently hardened by heat and pressure. A central bushing 4 is preferably provided so that the completed commutator may be secured to the shaft. For high voltages, mica sheets may be inserted between the segments before the moulding operation. Specification 256,045 is referred to.
