Abstract

220,755. Lancashire Dynamo & Motor Co., Ltd., and Bramley, C. P. June 18, 1923. Coils and conductors, securing in open rotor slots. Relates to the rotors of high-speed dynamo-electric machines in which the windings are wedged in radial slots. The conductors E are consolidated in the slots A by pressure applied to auxiliary slot wedges D which engage with auxiliary reaesses a<2> in the walls of the slots as the pressure is applied and hold the conductors in the consolidated position after the pressure is removed, the main slot wedges C being then fitted in the usual main recesses a<1>, the main wedges making joint with and backing up the auxiliary wedges throughout their length. The ends f<1>, f<2> of the slot insulation overlie one another and a strip of insulation G is positioned between them and the auxiliary wedge. The auxiliary wedges may be corrugated, and when this form is employed additional slot insulation is provided and the strip F may be of metal.
