Rotor for an electrical machine, electrical machine for driving a vehicle, and vehicle

A rotor for an electrical machine, comprising:

• a rotor core with a plurality of radially outwardly extending rotor legs;
• a number of exciter windings corresponding to the number of rotor legs, each wound around one of the rotor legs;
• and
• a separating device, having:
• a number of separating portions corresponding to the number of rotor legs, which are arranged between a respective pair of adjacent exciter windings and extend axially between two opposing end faces of the rotor,
• a first annular connecting portion which connects together the separating portions at one of the end faces, and
• a second annular connecting portion which connects together the separating portions at the other of the end faces,
• wherein the separating device is formed by a first part and by a second part which are joined together by means of a form-fit and/or force-fit connection, wherein the first part comprises at least the first connecting portion and at least partially the separating portions, and the second part comprises at least the second connecting portion,
• wherein a respective separating portion is divided in an axial direction into a first partial separating portion and a second partial separating portion, wherein the first part of the separating device comprises the first partial separating portion of the respective separating portion, and the second part of the separating device comprises the second partial separating portion of the respective separating portion,
• wherein each of the first and second partial separating portions comprises a frontal first end and a second end axially opposite the first end, and the connection between the first part of the separating device and the second part of the separating device is formed by the second ends of the partial separating portions of the respective separating portion,
• wherein the second end of one of the partial separating portions of the respective separating portion is on the radial outside of an axial first protrusion, and the second end of the other of the partial separating portions of the respective separating portion is on the radial inside of an axial second protrusion, and
• wherein the first protrusion has a radially inwardly pointing first extension, and the second protrusion has a radially outwardly pointing second extension which engages in the first extension.
