Abstract
An apparatus and a method for influencing electromagnetic forces of an electric traction motor, a higher-order harmonic () being superimposed on an actuating variable (u) for the electric traction motor in a manner which is dependent on a rotational speed of the electric traction motor, a torque of the electric traction motor, a temperature at the electric traction motor, or a three-phase current or a three-phase voltage of the electric traction motor for the generation of a resulting actuating variable (u), the electric traction motor being actuated in a manner which is dependent on the resulting actuating variable (u), and the actuating variable (u), the harmonic () and the resulting actuating variable (u) characterizing an actuating current or an actuating voltage.
