A rotor includes a magnetic field-generating component for producing a rotor magnetic field and a rotor core for holding the component. The rotor core has an annular rotor yoke and at least two rotor poles which are arranged on the rotor yoke and are configured in multiple parts, and each of which has a rotor tooth integrally formed on the rotor yoke and a pole shoe that is separate from the rotor tooth for arranging the component on the corresponding rotor tooth. The pole shoes are pressed radially against the respective rotor tooth, and the rotor has auxiliary joining parts, each of which is configured to fix at least one pole shoe to the corresponding rotor tooth by a force-fitting connection and which are at least partly arranged in respective pole gaps between two rotor poles and are secured to the rotor yoke by at least one connection element.
