  • Method and apparatus for processing a motor signal, having current ripple, of a DC motor
    Patent number: 8725440
    Abstract: In order to process a motor signal (Ia, Um) of a DC motor (4), in particular of an adjustment drive of a motor vehicle, the armature current (Ia) and the motor voltage (Um) of the DC motor (4) are detected and used for determining the back-emf (E) of the DC motor (4), wherein the determined back-emf (E) is used to generate a useful signal (Sf, SEFL), which is in particular speed-proportional, from the armature current signal (Ia) for position sensing or for evaluating an excess force limitation.
    Type: Grant
