Claim Text:
1. A system for cooling a dynamoelectric machine, the system comprising: a coolant medium inlet; a coolant medium outlet; a fan connected to a rotor of the dynamoelectric machine, the fan configured to provide a flow of a coolant medium through the dynamoelectric machine; a flow control device configured to control the amount of the coolant medium passing through the dynamoelectric machine by controlling an opening area of at least one of the coolant medium inlet and the coolant medium outlet; and a winding temperature measurement system configured to measure and detect the temperature of one or more windings in the dynamoelectric machine, in response to detecting that the temperature of the one or more windings in the dynamoelectric machine is above a predetermined level, the winding temperature measurement system is configured to control the flow control device by adjusting the opening area of at least one of the coolant medium inlet and the coolant medium outlet to at least one of reduce windage loss and control coolant medium pressure within the dynamoelectric machine.
