Systems and methods provide active control of rotor cooling. In a number of embodiments, a system includes a controller coupled with an electric machine having a rotor. The controller evaluates parameters related to the electric machine for flow rate requirements of the rotor, where the flow rate requirements relate to cooling of the rotor. A flow rate of a fluid for cooling the rotor is computed, where the flow rate is based on a composite of the flow rate requirements. A control valve signal is delivered to set a control valve to supply the flow rate to the rotor based on the parameters.
