Abstract

1,091,202. Dynamo-electric machine cores. C. A. PARSONS & CO. Ltd. Dec. 16, 1964 [Sept. 17, 1963], No. 36586/63. Heading H2A. In a synchronous A.C. machine, e.g. a large 2-pole turbo-generator, heating due to stray losses around the stator core end structure is minimized by individual laminations 2b of the laminated core end portions having a thickness less than that of the individual laminations 2b<SP>11</SP> in the remainder of the core. The thinner laminations 2b<SP>1</SP> may be of equal thickness, or graded thickness reducing towards the core ends; in addition their outside diameter may be progressively reduced as at B towards the core ends, they may have interspersed Cu or A1 sheets (6), Fig. 3, which may be cooled by hydrogen, water or oil circulated through passages therein, they may have different magnetic characteristics from the remainder laminations 2b<SP>11</SP>, and the machine may include known magnetic shields.
