Abstract

982,118. Dynamo-electric machines. GENERAL ELECTRIC CO. Ltd. April 17, 1963 [April 17, 1962], No. 14875/62. Heading H2A. Rectifiers 4, e.g. semi-conductor mounted for rotation with the shaft 7 of an exciter machine 2 for a brushless dynamo-electric machine, e.g. alternator, are secured in pairs to a plurality of mutually electrically insulated heat sinks 11 which are disposed about the shaft on a support 8 carried by the shaft and each provided with outwardly-projecting fins 16 extending generally parallel with the shaft axis so as to constitute a ventilating fan for cooling the exciter machine as well as the rectifiers. The latter may be arranged as a 3-Ph. bridge and the support formed as a spider having three arms to the extremity of each of which is bolted a respective heat sink 11 which also forms the A.C. terminal of a forward and reverse polarity rectifier pair. The exciter machine has a stator field winding 1 D.C. energized by an automatic voltage regulator in dependence on the stator output of the alternator, and the 3-Ph. starconnected rotary armature winding 3 of the exciter machine is connected to the rotary field winding of the alternator via the rectifiers 4, arcuate-shaped metal members 17, and leads extending along the alternator shaft. Instead of being in a separate casing 6 the exciter windings 1, 3 may be within the alternator.
