Abstract

The invention relates to a method for determining a motor constant (Km) of an electric machine (7), in particular an actuator arrangement (6), wherein at least one excitation signal (Im) with at least one DC component (I0) and one AC component (Ik) is specified, wherein the machine (7) is controlled with the excitation signal (Im), wherein at least one actual value of a motor current of the machine (7) and one actual value of a rotation rate (ω) of a rotor shaft of the machine (7) are determined, and wherein the motor constant (Km) is determined as a function of the excitation signal (Im) and the actual values.
