Cooling system for an electric motor

Abstract

A stator housing has an annular wall including a first end, a second end, an outer surface and an inner surface defining an interior cavity. A stator is arranged within the interior cavity. The stator includes an outer surface portion, a first end turn and a second end turn. A coolant annulus extends about at least a portion of the stator housing. The coolant annulus includes at least one coolant spray passage arranged to direct a spray of coolant at one of the first end turn and the second end turn. A coolant seal and distributor is coupled to the stator housing at the first end sealing against the stator. The coolant seal and distributor includes one or more coolant spray nozzles arranged to direct a spray of coolant onto the other of the first end turn and the second end turn.
