Abstract

Embodiments of the invention provide an electric machine module and a method for cooling an electric machine. The apparatus and method include providing the electric machine including a rotor and a stator with stator end turns and enclosing at least a portion of the electric machine within a housing. The method also includes introducing a coolant into a machine cavity, directing the coolant toward the stator end turns, and returning a portion of the coolant which flows past the stator end turns back toward the stator end turns using a rotating agitator member operatively coupled to the rotor.
