Abstract
An electric machine includes a fluid control system that is configured to regulate the flow rate of fluid to the electric machine. The machine includes a sensor that senses a parameter representative of cooling required by the machine. The sensor supplies a sensor signal to a control unit, which in turn supplies a flow control signal to a flow regulator. The flow regulator, in response to the flow control signal, controls the flow rate of fluid to the machine to what is needed for effective cooling at current operating conditions. As a result, windage losses and pumping power requirements in the machine are reduced, and machine efficiency is increased.
