Abstract

A method operates a brushed commutator motor of an adjusting drive in a motor vehicle, particularly a window lifter, having a rotor and having a stator. An angular position of the rotor with respect to the stator is determined. The angular position is used to determine a ripple within the torque, which ripple can be expected on the basis of the commutation. The motor current is adapted such that the amplitude of the ripple that can be expected remains below a determined limit value.
