Abstract

1343413 Coils for dynamo-electric machines JOSEPH LUCAS (INDUSTRIES) Ltd 15 July 1971 [18 July 1970] 34957/70 Heading H2A In a stator assembly comprising electrically interconnected windings mounted on respective polepieces carried by a yoke, each winding 11 comprises a plurality of convolutions of metal foil strip 12, adjacent convolutions being separated by a layer of insulating material, and an end portion 13 of each winding is stapled to an end portion of an adjacent winding to provide the required electrical connection. The metal foil strip is aluminium, this being interleaved with a strip 14 of melamine. The end portions 13 of each winding are folded over, as shown, and project beyond the winding to facilitate stapling.
