Abstract: Systems and methods for a sealing assembly for a motor cooling system are herein described. In one example, the sealing assembly includes an elastomeric seal interposed radially between a lateral surface of a stator of an electric motor and a sealing ring. The elastomeric seal includes a plurality of openings configured to receive a plurality of end windings of the stator and a molded annular bead arranged to define an inner diameter of the elastomeric seal and configured to be compressed axially to further separate a coolant for the plurality of end windings from a rotor.

Abstract: Stator sealing systems are disclosed herein for sealing coolant fluid that cools a stator from entering a rotor cavity within a bore of the stator. The stator sealing system includes sealing rings positioned at sealing interfaces at both ends of the stator provided by either bend lamination layers on both ends of the stator or a bore sleeve positioned in the bore.

Abstract: Systems for preventing leakage of coolant in an electric motor cooling system. In one example, a sealing ring configured with a stator seal may be integrated as part of a sealing assembly of a cooling system. The sealing ring includes a flange, a plurality of channels that is positioned radially on the sealing ring, a plurality of notches, a plurality of surface grooves, an elevated region that are configured with anchors that retain the seal, a depressed region wherein a plurality of retention posts is positioned therein, a peripheral groove positioned on a peripheral edge of the sealing ring and spaced between two sides of the sealing ring, and wherein the seal is integrated with an inner edge of the sealing ring and extends from the inner diameter to the elevated region of the sealing ring.
