Abstract:
In various embodiments, systems, apparatuses and methods are provided to distribute coolant to an electric motor. The apparatus includes a pan configured with a set of holes for coolant flow; an assembly including a set of bar linkages, a set of discs, and a single actuator motor wherein the assembly is attached to the pan wherein the single actuator motor is linked via bar linkages to discs that enable configuring a planar angle of the pan to obtain an optimum hole location of holes for coolant flow; and in response to external disturbances to the apparatus that redirect the coolant flow from the target region of the electric motor, the single actuator motor is controlled by an algorithm to change the planar angle of the pan to obtain the optimum hole location to direct coolant flow to the target region of the electric motor.
