Abstract

1352814 Cooling electric machines NAUCHNO - ISSLEDOVATELSKY I EXPERIMENTALNY INSTITUT AVTOMOBILNOGO ELEKTROOBORUDOVANIA I AVTOPRIBOROV 5 April 1972 15568/72 Heading H2A In an air-cooled electric machine, e.g. a vehicle generator, comprising a stator 1 having windings 2 and mounted in bearing housings 6, 7 having vent ports 17, 18 to allow the passage of cooling air through the internal space of the machine, the internal cylindrical surfaces of the housings have vent passages 8 which are disposed partly adjacent the stator winding end portions, are positioned obliquely with respect to the longitudinal axis of the machine, and which intercommunicate along the outside of the stator. This intercommunication is via an annular chamber 9, and the air flow is impelled, by a fan 11, through a casing 15 covering control circuit components 14, to divide into two flows respectively through the rotor/stator air gap, and around the winding end portion and through the chamber 10. The vent passages are circumferentially staggered in order to increase the flow path length.
