Abstract
An electric machine has a stator and a rotor which is separated from the stator by an air gap. The rotor has at least one first rotor body, which has a first group of permanent magnets, and at least one second rotor body, which is arranged at an axial distance from the first rotor body) and has a second group of permanent magnets. A rotor shaft is coupled to the first rotor body and the second rotor coaxially within the first rotor body and the second rotor body so as to transmit a torque. At least the first rotor body is mounted on the rotor shaft so as to be rotatable relative to the second rotor body against the effect of a first torsional stiffness by means of a mechanical field-attenuation mechanism.
