ABSTRACT:
Difficulties in cooling the rotor (28) of a dynamoelectric machine carrying a rotating rectifier (54) are avoided by providing a coolant inlet 68 extending to the interior of a rectifier housing 50 through which the coolant may flow to emerge from a port 66 in the housing 50 and flow via an annulus 52 within the rotor shaft 30 to conduits 98 to cool the rotor windings 48. The coolant is returned to the interior of the rotor shaft 30 and ultimately to a coolant outlet 84.
