Abstract
The invention relates to a drive configuration for the motorized displacement of a displacement element of a motor vehicle, at least one drive having an electrical drive motor, in particular a DC motor, and a drive controller, which is associated with the drive and connected to a supply voltage U, being provided, the drive not being designed as self-locking, so that in the case of a non-motorized displacement of the displacement element, the drive motor operates as a generator and generates a generator voltage U. It is proposed that the drive controller is equipped with an overvoltage protector, which can be triggered by exceeding a limiting supply voltage U, and that the configuration is further made so that the overvoltage protector can additionally be triggered by a non-motorized displacement of the displacement element if a limiting generator voltage Uis exceeded.
