Rotor having a slot wedge, electric machine, motor vehicle, and method for producing a rotor

A rotor for an externally excited electric machine of a motor vehicle, comprising:

• an annular yoke with a yoke outer side directed outward in the radial direction of the yoke;
• a plurality of pole teeth on the yoke outer side, the plurality of pole teeth are arranged and/or formed spaced apart from one another in the circumferential direction of the yoke, each of the plurality of pole teeth further comprising:
• a pole shaft;
• and
• a pole shoe;
• wherein the pole shaft is formed between the yoke outer side and the pole shoe;
• a rotor winding arranged on each pole shaft;
• a slot wedge arranged in a slot between the rotor windings of two adjacent pole teeth;
• and
• a layer of an elastomer on an outer side of the slot wedge, the layer of elastomer facing the respective rotor winding, against which the rotor winding bears at least partially and/or in portions.
