- a slot lining in a respective slot of the stator core, which liner surrounds the stator winding accommodated in the slot.
- a slot lining is formed, for example, from an insulating paper or other electrically insulating, flat body corresponding to the Dimensions of the groove is folded or bent.
- a first end section and a second end section of the slot lining overlap. According to the required clearances and creepage distances, the cross-sectional length of the first end section, which overlaps the second end section, must be long enough.
- US 2012/0 293 037 A1 discloses a rotating electric machine with a rotor and an annular stator arranged around the rotor.
- the stator includes slots extending in the radial direction of the stator, a stator core in which the slots are formed spaced apart from each other in the circumferential direction, insulating paper accommodated in the slots, and coils arranged in the slots so as to pass through the insulation paper are insulated from the stator core.
- the insulating paper has bent portions overlapping each other in an overlapping portion. As a result, a radially inner side of the insulating paper is closed.
- the invention is based on the object of specifying a possibility for operating an electric machine for driving an electric vehicle, which ensures sufficient air gaps and creepage distances in its slots even at high voltages.
- the invention provides for the stator core of the type mentioned at the outset that the first receiving space adjoins the second receiving space in the circumferential direction and is delimited by the first groove wall.
- a stator core for accommodating a stator winding and slot liners is proposed.

- the second accommodation space is set up to accommodate the stator windings and sections of the slot liner lying outside the first end section.
- the first receiving space adjoins the second receiving space in the circumferential direction.
- the first receiving space is delimited by the first groove wall.
- the invention is based on the idea of providing the second receiving space for the overlapping first end section on the side of the first groove wall, so that its entire radial extent can be used to receive the first end section.
- the radial extension of the groove is greater than its extension in the circumferential direction, there is a considerably larger space for accommodating the first end section than if the the first end section is located between the groove walls on the side of the groove facing away from the groove bottom.
- the invention advantageously makes it possible to realize longer clearances and creepage distances along the end sections of the slot lining and thus to provide a higher voltage present at the stator windings during operation of an electrical machine comprising the stator core.
- the stator core is preferably formed from a large number of axially layered and/or electrically insulated individual laminations.
- the stator core can also be referred to or considered as a laminated stator core.

- the slot opening is preferably delimited in the radial direction by tooth tips of the teeth.
- the stator core can also include a yoke, which surrounds the slots radially on the outside and forms the bottom of the slot.
- the first groove wall and/or the second groove wall can transition into the groove base in a rounded manner in cross section.
- the first receiving space can also be set up to form a free space between the second receiving space and the first groove wall beyond its area in which it receives the first end section.
- the first groove wall extends at least in sections along a first straight line, the second groove wall along a second straight line and the bottom of the groove along a third straight line, so that the first straight line and the second straight line are the legs of a trapezoid whose base is the third line lies, form, with the trapezoid a first interior angle enclosed by the first straight line and the third straight line, and a second interior angle enclosed by the second straight line and the third straight line.

- a fourth interior angle which is enclosed by the further straight line and the fourth straight line, can be greater than 90°.
- the fourth interior angle can be 360° minus the sum of the first and further interior angles. It is preferred if the first interior angle is smaller than the second interior angle. This results in an extension of the groove base in cross-section to form the first receiving space.
- the first interior angle can be dependent on the length of the first end section. In particular, the greater the length of the overlap of the end sections, the smaller the first interior angle.
- the first interior angle can be perpendicular. This is particularly advantageous in connection with the first groove wall having the first and the second section.
- the second interior angle is right-angled.
- conventional stator cores with essentially rectangular slots can be expanded by the first receiving space with little effort.
- the first end section is longer in cross-section than the bottom of the groove and/or than a radially innermost distance of the groove walls. As a result, the space running essentially in the radial direction is used efficiently for lengthening the air gaps and creepage distances.
