Abstract
A motor is provided including a stator core having a plurality of stator fins projecting outwardly from the stator core. A plurality of stator cooling channels is defined between adjacent stator fins. A flow mixer ring is axially aligned with the stator core and separated therefrom by an axial gap. The flow mixer ring includes a plurality of ring fins projecting inwardly from an interior surface and a plurality of ring cooling channels defined between the plurality of ring fins. The plurality of ring fins extends from a first surface over at least a portion of an axial length of the flow mixer ring.
