Stator for an electric machine, production method for such a stator in an electric machine

A stator for an electric machine, comprising:

• a ring-shaped stator body defining a longitudinal centre axis;
• a plurality of electrically conductive stator windings disposed radially inside of the stator body and connected to the stator body, the plurality of stator windings projecting axially beyond the stator body at each axial end such that the stator body is flanked axially on a first side by a ring-shaped first axial overhang and on a second side by a ring-shaped second axial overhang;
• a plastic injection moulded body at least partially encasing the plurality of electrically conductive stator windings;
• and
• a plurality of radial cooling apertures through which coolant is flowable, the plurality of radial cooling apertures penetrating at least one of the first axial overhang and the second axial overhang.

A stator for an electric machine, comprising:

• a ring-shaped stator body defining a longitudinal centre axis;
• a plurality of electrically conductive stator windings arranged on an inner circumferential surface of the stator body, the plurality of stator windings projecting axially beyond the stator body at each axial end such that the stator body is flanked axially on a first side by a ring-shaped first axial overhang and on a second side by a ring-shaped second axial overhang;
• a plastic injection moulded body at least partially encasing the plurality of stator windings and connecting the plurality of stator windings to the stator body;
• a plurality of radial cooling apertures through which coolant is flowable, the plurality of radial cooling apertures penetrating at least one of the first axial overhang and the second axial overhang;
• and
• a fluid path through which the coolant is flowable, the fluid path including i) at least one first section extending axially through the stator body and ii) at least one second section extending radially through at least one of the plurality of radial cooling apertures;
• wherein at least some of the plurality of radial cooling apertures are delimited by the plastic injection moulded body and are radially open.
