Multipart rotor for an electric machine, electric machine, and motor vehicle

A rotor for an electric machine of an electrically drivable motor vehicle, the rotor comprising:

• a magnetic field-generating component for configuring a rotor magnetic field;
• and
• a rotor core for holding the magnetic field-generating component, wherein:
• the rotor core has an annular rotor yoke and at least two rotor poles which are disposed on the rotor yoke, are configured in multiple parts and have in each case one rotor tooth which is configured integrally with the rotor yoke, and a pole shoe which is separate from the rotor tooth for disposing the magnetic field-generating component on the rotor tooth,
• each pole shoe is pressed radially against a respective rotor tooth,
• in order to press each pole shoe radially against the respective rotor tooth, the rotor has auxiliary joining parts which are configured to fix each pole shoe to the respective rotor tooth by way of a force fit,
• the auxiliary joining parts are at least partially disposed in respective pole gaps between two rotor poles,
• the auxiliary joining parts are fastened to the rotor yoke by at least one connecting element,
• each pole shoe has a circular-segmented cross section which is delimited by a chord and an arc, and sides of the pole shoes that are assigned to the chords are disposed on sides of the rotor teeth that lie radially opposite the rotor yoke, and
• the magnetic field-generating component has rotor windings with pre-wound winding conductors which are configured to be pushed onto the rotor teeth.
