Abstract
Various methods and systems are provided for an electric motor including a coolant jacket molded to a stator. In one embodiment, an electric motor comprises a stator, and a coolant jacket molded as a single, unitary piece in sealing engagement against an outer perimeter of the stator, with a first end of the coolant jacket forming a first integrated spray ring.
Claims16
An electric motor, comprising:
- a stator;
- a coolant jacket molded as a single, unitary piece in sealing engagement against an outer perimeter of the stator, with a first end of the coolant jacket forming a first integrated spray ring;
- and
- a plurality of feed channels and a plurality of outlet channels formed by the coolant jacket,
- wherein each feed channel of the plurality of feed channels fluidly couples to an annular clearance disposed between an outer circumferential portion of the coolant jacket and an outer circumferential surface of the stator, with the annular clearance closed by sealing engagement of the first integrated spray ring with the outer circumferential surface of the stator.

An electric motor, comprising:
- a stator;
- a coolant jacket enclosing the stator and molded in place against an outer circumferential surface of the stator;
- an annular coolant passage formed between the coolant jacket and the outer circumferential surface and surrounding the stator;
- and
- a feed channel a plurality of feed channels and a plurality of outlet channels formed by the coolant jacket, wherein each feed channel of the plurality of feed channels extends axially through a first integrated spray ring parallel to a central axis of the first integrated spray ring, the plurality of feed channels extending to the annular coolant passage through the first integrated spray ring of the coolant jacket molded to the outer circumferential surface.
