Abstract
A system for cooling a dynamoelectric machine is provided. The system includes a coolant medium inlet, a coolant medium outlet and a fan connected to a rotor of the dynamoelectric machine, The system further includes 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. The system further includes a winding temperature measurement system configured to measure the temperature of one or more windings in the dynamoelectric machine, and control the flow control device by adjusting the opening area of at least one of the coolant medium inlet and the coolant medium outlet based on the temperature of the windings in the dynamoelectric machine to at least one of reduce windage loss and control coolant medium pressure within the dynamoelectric machine.
