Title:
METHOD AND DEVICE FOR PROCESSING A MOTOR SIGNAL OF A DC MOTOR, HAVING CURRENT RIPPLES
Document Type and Number:
WIPO Patent Application WO/2010/028736
Kind Code:
A3
Abstract:
According to the invention, for processing a motor signal (Ia, Um) of a DC motor (4), in particular an adjusting drive of a motor vehicle, the armature current (la) and the motor tension (Um) of the DC motor (4) are detected and are used to determine the counter induction tension (E) of the DC motor (4). Using the determined counter induction tension (E), a useful signal (Sf,SÜKB), in particular proportional to the rotational speed, is produced from the armature current signal (Ia) for detecting the position and/or for evaluating an excess force limitation.
