Abstract

A stator core is provided that can define a plurality of core slots in a surface thereof. The core slots can extend between a first and a second end portion of the stator core. A winding can be housed in the core slots. The winding can define a channel through at least a portion thereof. A cooling system can be operably coupled with the channel and can be configured to move a cooling fluid through the channel. A turbulator can be positioned within the channel. The turbulator can be within a flowpath of the cooling fluid and can be integrally formed with the winding.
