Abstract
Embodiments of the invention provide an electric machine module including a module housing, which can at least partially define a machine cavity. In some embodiments, an electric machine can include a stator assembly and a rotor assembly and can be positioned in the machine cavity. In some embodiments, the module housing can include a coolant transport network, which can include at least one passage in fluid communication with at least one first annulus and at least one second annulus. In some embodiments, the first annulus can be substantially axially adjacent to an axial end of the stator assembly and the second annulus can be substantially axially adjacent to an axial end of the rotor assembly. In some embodiments, the annuli can include a plurality of annulus apertures.
