Abstract
In order to process a motor signal (I, U) of a DC motor (), in particular of an adjustment drive of a motor vehicle, the armature current (I) and the motor voltage (U) of the DC motor () are detected and used for determining the back-emf (E) of the DC motor (), wherein the determined back-emf (E) is used to generate a useful signal (S, S), which is in particular speed-proportional, from the armature current signal (I) for position sensing or for evaluating an excess force limitation.
