Stator, method for producing a stator, fluid guide body, and electric machine

A method for producing a stator for an electric machine, comprising:

• providing a cylindrical stator with an inner diameter, in which a rotor with an outer diameter can be inserted, thereby forming a cylindrical air gap, and the stator has a plurality of stator teeth, each stator tooth defining a respective stator groove which is located between adjacent stator teeth in the circumferential direction, extends in the radial direction, runs through the stator in the axial direction, and comprises two groove lateral walls and a groove base, into which an energizable winding is inserted, said winding comprising a plurality of conductors, wherein the winding exits the stator at at least a first end face, thereby forming a first cylindrical winding head and wherein a cooling fluid can flow through the stator from the first end face, wherein at least a first conductor of the first winding head has a first contacting section that extends out of the winding head in the axial direction;
• providing a cylindrical fluid guide body through which the cooling fluid can flow, wherein the first winding head can be at least partly surrounded by the fluid guide body;
• arranging a first electric contacting means on the fluid guide body, through which the first contacting section of the first electrical conductor can at least partly pass in an electrically contacting manner;
• and
• arranging the fluid guide body on the first winding head, thereby forming the electric contacting of the first contacting section with the first electric contacting means.

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, wherein a rotor with an outer diameter is inserted into the cylindrical ring to form a cylindrical air gap;
• and
• a plurality of stator teeth, each stator tooth defining a respective stator groove located between adjacent stator teeth in the circumferential direction, extends in the radial direction, runs through the stator in the axial direction, and comprises two groove lateral walls and a groove base, wherein an energizable winding is inserted into a respective stator groove, the winding comprising a plurality of conductors, wherein the winding exits the stator at a first end face and forms a first cylindrical winding head, wherein a cooling fluid flows through the stator from the first end face, wherein the stator has a cylindrical fluid guide body through which the cooling fluid flows and which at least partly surrounds the first winding head, wherein at least a first conductor of the winding head has a first contacting section that extends out of the winding head in the axial direction and at least partly passes through a corresponding first electric contacting means arranged on the fluid guide body in an electrically contacting manner, wherein the first electric contacting means is coupled to a first electric connection means in an electrically conductive manner, by means of which an electric contact is established between the first conductor and an inverter energizing the winding via an outer side of the fluid guide body facing away from the cooling fluid.
