Abstract: A drive for a leaf of a door, window, or the like, including a mechanical energy store (16) configured to store energy during an opening movement of the leaf and expend energy during a closing movement of the leaf, an electric motor (18) operatively connected to the leaf via a motor shaft (20), the electric motor (18) operated as a generator to dampen the opening movement and the closing movement. The electric motor including a control unit configured to control the electric motor, wherein a drive behavior of the control unit is repeatedly and variably adaptable to a current need of a user.

Abstract: A drive unit for closing a leaf of a door or a window comprises an energy accumulator for providing a closing force for closing the leaf, a damping device which counteracts the closing force and has an electric motor which can be operated as a generator and can be coupled to an actuating element of the drive unit, and a control device for controlling the electric motor. The control device is designed to determine a nominal path curve which indicates a position of the leaf or a closing speed of the leaf in dependence upon time, and to perform the control of the electric motor in order to damp the closing movement of the leaf on the basis of the established target path curve.

Abstract: A drive for a leaf of a door, window, or the like, comprising at least one mechanical energy store, which is charged by an opening movement of the leaf and discharged by a closing movement of the leaf, at least one electric motor, which is operatively connected to the leaf via at least one motor shaft and can be operated as a generator in order to dampen the leaf movements, and a control and/or regulator electronics unit for controlling the electric motor. The control and/or regulator electronics unit comprises means via which the drive behaviour can be variably specified repeatedly by a respective user and/or via which the drive behaviour can be variably adjusted repeatedly in accordance with the behaviour of a respective user.
