Patent ID: 8901789

Claim:
An electric machine module comprising: a housing including a sleeve member coupled to at least one end cap, the housing defining a machine cavity; an electric machine positioned within the machine cavity and at least partially enclosed by the housing, the electric machine comprising a brushless configuration, a central axis of rotation, a stationary support member coupled to a wall of the housing and extending into the machine cavity, and a stator assembly comprising a plurality of laminations and substantially circumscribing at least a portion of a rotor assembly, the stator assembly including at least one recess positioned at the outer diameter of at least one of the plurality of laminations; a cooling system at least partially positioned within portions of the housing and support member, the cooling system including a first inlet disposed through a portion of the housing, a first channel at least partially disposed within the support member and oriented substantially parallel to the central axis of rotation, the first channel being in fluid communication with the at least one inlet, and at least one second channel disposed within the support member and oriented substantially perpendicular to the central axis of rotation, the at least one second channel being in fluid communication with the first channel and the machine cavity; and a drain aperture disposed through at least a portion of the housing, the drain aperture in fluid communication with the machine cavity; and wherein the housing comprises at least one drain guide substantially immediately adjacent to the drain aperture and adjacent to the at least one recess, the at least one recess positioned substantially radially inward from the at least one drain guide.
