Stator and electric machine

A stator for an electric machine comprising:

• a cylindrical ring with an inner diameter, a rotor with an outer diameter is inserted into the cylindrical ring to form a cylindrical air gap;
• a plurality of stator teeth, each stator tooth defining a respective stator slot located between adjacent stator teeth in the circumferential direction, extending in the radial direction, running through the stator in the axial direction, and comprising two slot side walls and a groove base,
• an energizable winding inserted into the stator slots, the winding comprising a plurality of conductors, a cooling fluid flowable through the stator from at least a first end face, and an attachment body arranged on the first end face and extending at least partly away from the first end face in the axial direction;
• and
• a cylindrical fluid guide body with an annular base and an inner casing extending outwards axially from the base and an outer casing extending outwards axially from the base, wherein the inner casing has an inner diameter greater than or equal to the outer diameter of the rotor, and wherein the inner casing and the outer casing of the fluid guide body are fixed to the attachment body,
• the attachment body including a cylindrical inner connection section on the inner diameter of the stator extending axially from the stator and to which the inner casing of the cylindrical fluid guide body is fixed,
• the attachment body including a cylindrical outer connection section extending outwards axially from the stator and to which the outer casing of the cylindrical fluid guide body is fixed.

A drive train comprising:

• an electric machine, the electric machine including a stator and a rotor, wherein the stator comprises:
• a cylindrical ring with an inner diameter, the rotor with an outer diameter is inserted into the cylindrical ring to form a cylindrical air gap;
• a plurality of stator teeth, each stator tooth defining a respective stator slot located between adjacent stator teeth in the circumferential direction, extending in the radial direction, running through the stator in the axial direction, and comprising two slot side walls and a groove base,
• an energizable winding inserted into the stator slots, the winding comprising a plurality of conductors, a cooling fluid flowable through the stator from at least a first end face, and an attachment body arranged on the first end face and extending at least partly away from the first end face in the axial direction;
• and
• a cylindrical fluid guide body with an annular base and an inner casing extending outwards axially from the base and an outer casing extending outwards axially from the base, wherein the inner casing has an inner diameter greater than or equal to the outer diameter of the rotor, and wherein the inner casing and the outer casing of the fluid guide body are fixed to the attachment body.
