Abstract

An electric machine can include a stator core having a plurality of core teeth that define a plurality of core slots in a surface thereof. A winding can be housed at least partially in the core slots. The winding can include a tube defining a channel through at least a portion thereof and one or more wires disposed along a surface of the tube that is opposite the channel. A cooling system can be operably coupled with the channel and configured to move a cooling fluid through the channel.
