Braking device
A braking device for a movable door wing comprising an electric motor operated as a generator wherein its motor shaft is rotatable by a movement of the door wing and which outputs a motion-dependent motor voltage, and a braking circuit to which the motor voltage is applied or can be applied and via which the electric motor can be short-circuited in order to dampen a movement of the door wing. In addition, it is provided that the braking device comprises a safety device with a current sensor which is designed to detect amperage generated by the electric motor. The safety device is designed to modify the braking circuit depending on the detected amperage in such a way that upon reaching or exceeding a predetermined or predeterminable overload amperage, the current in the braking circuit is reduced.
