An electric-motor adjustment drive is provided for an adjustment element in a motor vehicle, in particular a window lifter, that has a drive module, which includes a pole pot that supports a motor shaft, and having an electronic module having a circuit board, which can be inserted into a housing of a brush holder, which housing is connected to the drive module. The circuit board is retained in an insertion plane perpendicular to the motor shaft by the housing of the brush holder in a form- and/or force-closed manner, wherein a number of contact elements for motor contacting and/or for interference suppression are arranged in the housing, which contact elements are contacted within the housing when the circuit board is inserted.
