  • a method is described for retracting an element driven by an electric motor within a predetermined movement distance between two block positions designed as an end stop to a block position, wherein when the driven element retracts into at least one of the two block positions the driven element is reached before reaching the mechanically defined position Block position is decelerated.
  • one block position is defined by the closed position of the disk and the other block position by the opened disk position.
  • a braking of the disc movement before reaching the lower, the open position of the disc kenn ⁇ characterizing block position is performed to bring the disc as gently as possible to its lower end stop.

  • On the other hand serves a gentle retraction of the disc in the Lower block position to avoid disturbing Anschlagge ⁇ noise, from which a user could possibly suspect a defect in its window regulator.
  • the electric motor In order to brake the driven element, the electric motor is de-energized and switched to a generator mode in order to observe the decreasing speed of the armature of the electric motor during coasting via the current signal generated by the electric motor due to its leakage, and depending on the size of the When the current signal is detected in the generator mode, the electric motor is energized again to the final position of the driven element in the block position.
  • a device for electrical braking of a collector motor has become known, in which by a control of the duty cycle through the winding first flows a current whose value is smaller than the current through the braking resistor, since because of the short control pulses Commutation of the motor current in the excitation circuits is not completely carried out.
  • the duty cycle is now chosen so large that the remindingkun ⁇ conditions on the braking resistor are very small, ie the braking resistor is effective almost at its full value.
  • an electromechanical drive is driven against a fixed stop, the components involved are braced in their bearings. When the drive is switched off, these components relax and in turn introduce mechanical energy into the drive. This can cause the drive to move undefined in the opposite direction.
  • a slow shutdown by continuous reduction of the applied voltage or power-controlled shutdown, for example, by a phase control is known.
  • these methods are not contractual for cost reasons and reasons of electromagnetic compatibility for motor vehicles. borrowed. It is also possible to use the motor as a brake by short circuiting immediately after energizing. This has the disadvantage that the short circuit must be done with high quality and accurate Tirning. This requires a lot of hardware and software.
  • the electromechanical component can therefore not be used arbitrarily in different environments. An interpretation of the hardware with economic components is usually not possible.
  • the object of the invention is to improve electromechanical systems.
  • the system gradually relaxes, so that no disturbing mechanical reactions occur and the electromechanical drive is always applied directly to the stop. It prevents the unwanted introduction of reaction forces into the electromechanical system.
  • the drive logic of the electromechanical drive is independent of the electrical environment such as the wiring or the hardware. As a result, the simple usability of the component in several components and series and a cost-optimal selection of drivers for the control is possible.

  • the internal mechanism is pressed against the bearings.
  • the mechanical system After switching off the electrical voltage, the mechanical system tries to move the electromechanical drive 15 back. To counteract this, after a predetermined driving time T of 500 ms, the cycled shutdown takes place according to the control characteristic curve in FIG. 2. The movement process of the cycled shutdown takes 250 ms under normal conditions. The masses are low, so that the drive runs only minimally. After the end of normal energization, the drive is short-circuited for a short time. The mechanical system of the electromechanical drive 15 relaxes and moves in the opposite direction to the direction of actuation. Now the system is controlled one or more times very short in the direction of actuation. Between the An ⁇ controls the electrical drive is shortge ⁇ each closed.

  • This is determined once for each electromechanical drive and stored in the controller 10 for all identical drives.
  • the time window for the clocked shutdown is not too small to choose so that the mechanical forces located in the electromechanical drive are reduced and the drive with minimum energy input to the desired stop applies.
  • the time window is not too big to choose.
  • 10-time clocking leads to a buzzing that the driver perceives as negative.
