Abstract
A wet cavity electric machine includes a stator core having two stator poles formed by a post and a wire wound about the post to form a stator winding, with the stator winding having end turns, and a rotor having two rotor poles and configured to rotate relative to the stator and a channel for liquid coolant to flow through the rotor, and at least one fluid port in fluid communication with the channel and the stator winding end turns wherein the end turns will be exposed to liquid coolant passing through the channel.
