Abstract
1448824 Cooling dynamo-electric machines LUCAS INDUSTRIES Ltd 5 Nov 1973 [18 Nov 1972] 53422/72 Heading H2A A dynamo-electric machine comprises stator and rotor windings cooled by a coolant which is directed through a passage 25 and apertures 26 in the rotor shaft 14 by a pump 27 driven by the rotor, the coolant subsequently gathering in a sump 32 which includes a heat exchanger 34. The alternator shown has two stators 15 and two rotors 18 whose field windings 19 are energized by the rectified output of an exciter 22. The coolant is oil which also lubricates the rotor bearings 13.
