Abstract

1496176 Rotors of electrical machines ROBERT BOSCH GmbH 16 May 1975 [6 Dec 1974] 20792/75 Heading H2A A rotor 13, formed from edgewise-wound sheet magnetic strip or from stacked magnetic laminations, has winding slots 14 each of which, as seen in cross-section perpendicular to the rotor axis, extends radially of said axis and has a radially inner base portion 15 which is a segment of a circle and leads radially outwardly into a trapezoidal portion 17 in which the slot width widens radially outwardly and which merges into a radially outer rectangular portion 18 in which the slot has substantially constant width and which leads to a radially outer open top. The slots 14 are lined with electrically insulating paper 3 and receive an impregnated winding 20 of aluminium, e.g. formed by two coil portions with wires 21 and 22 respectively, the wires 21 being shaped prior to insertion so that the base portions 15 and at least the trapezoidal portions 17 are substantially filled thereby.
