Method of controlling door actuators and device therefor

Abstract

Abstract The present invention relates to a method of controlling door drives, especially drives for garage doors and the like, and to a drive for doors, especially for garage and entrance gates, with an electrically operated drive motor (4), devices for the transmission of force from the motor to the door or gate and devices (2, 8, 10) for starting and stopping the drive motor at least in its two end positions, that is to say in a completely closed and in a completely opened state of the door or gate. In order to provide a method of controlling door (gate) drives and also a corresponding drive or a control which are to be protected in a relatively simple way against faults of any kind and which, if possible, also guarantee a well matched energy supply, without high power losses, for an electric drive motor, it is proposed, according to the invention, that the position of the door or gate be detected in each state of motion, and that the energy supply of a drive motor be regulated in dependence on the detected door (gate) position or that the motor, the door or gate and/or the force-transmission devices be provided with a position indicator which assumes a state detectable by a measuring unit (3) and clearly assigned to a particular door (gate) position, that a measuring unit (3) be provided for detecting this position, and that an output of the measuring unit (3) be connected directly or indirectly to a control part (7, 8, 9, 10) which controls the energy supply to the drive motor. <IMAGE>
