Abstract (en)
[origin: WO9837622A1] A drive unit for electrically operated doors, windows, screening devices and the like, comprises a drive unit casing (5) containing a motion transfer member (4) in engagement with a reversible drive motor (1) with an associated motor control circuit. The drive unit is designed as a program controlled unit with a microprocessor (6) with an associated memory in which as operating parameters for the drive motor (1) among other a predetermined maximum current supply is stored. The microprocessor is programmed for calculation of the current maximum current on the basis of the measured motor current and for initiating a reduction of the motor voltage and thus the motor speed, when the maximum current consumption is reached.
