Abstract
An electric propulsion motor system includes a cylindrical stator and rotor, a fluid circulation system providing pressurized fluid, and conductors within winding slots. The stator has a yoke and a plurality of teeth extending radially inward from the yoke, with winding slots defined between adjacent teeth. Respective tooth tips extend circumferentially into adjacent winding slots and are radially adjacent to a first conductor within the winding slot, with a first channel through which pressurized fluid flows.
