Abstract: An apparatus for active thermal management of transmission lubricant includes a transmission having a housing and a rotating gear. A baffle arrangement is disposed within the housing operative to shroud a portion of the rotating component and direct transmission lubricant flow through at least one route. A heat exchanger disposed in the at least one route is operative to transfer thermal energy from a heat source to the transmission lubricant.

Abstract: 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.

Abstract: A motor includes a housing with a stator mounted to the housing. A drive shaft is rotatably mounted within the housing by a pair of bearing assemblies, the pair of bearing assemblies each including an inner bearing race and an outer bearing race. A rotor is mounted to the drive shaft. The drive shaft includes a longitudinal oil supply passage therein, the drive shaft including a first radial passage communicating with the longitudinal oil supply and extending to the inner race of a first one of the pair of bearing assemblies and a second radial passage communicating with the longitudinal oil supply and extending to the inner race of a second one of the pair of bearing assemblies. The inner race of the pair of bearing assemblies each include at least one lube hole.
