A system including an air turbine starter having a housing defining an air flow path between an inlet and an outlet. A turbine shaft located in the housing and a plurality of blades coupled to the turbine shaft and disposed in the primary air flow path. An electric motor within the housing, and an outer surface of the electric motor defining a portion of the primary air flow path, the electric motor having a drive shaft. A clutch assembly within the housing to selectively couple the electric machine drive shaft and the turbine shaft. Further, a valve to, when opened, fluidly couple an ambient air supply to the inlet and a controller to, when the electric motor is activated, open the valve to enable ambient air to flow through the primary air flow path and over the outer surface of the electric motor.
