Abstract

The invention relates to an electric motor drive for a leaf, in particular a rotary leaf, of a door or window. The electric driver includes: a housing; a driven shaft which can be rotatably supported in the housing and which can be coupled to the door leaf or sash or frame; an engine that is used for driving the driven shaft; a spring unit for providing a closing moment, which is tensioned during a corresponding opening movement of the door leaf or window sash and released during a corresponding closing movement of the door leaf or window sash; and the control device that is used for controlling the engine. The control device is designed to: actuate the engine in a corresponding manner to generate a basic closing moment during a corresponding opening movement of the door leaf or window sash; at least substantially compensate a corresponding opening angle-dependent spring force of the spring unit by means of the base closing torque; form an additional opening moment at least when the door leaf or window sash is manually opened and the control device is supplied with a corresponding opening command.

Description

[0001] This application is a divisional application based on the Chinese patent application with the application number 201710032707.4, the application date is January 18, 2017, and the invention name is "motor drive". technical field [0002] The invention relates to an electric motor drive for a door or window leaf, in particular a rotary leaf, with a housing, with a rotatable mount in the housing and which can be coupled to a door or window leaf or a frame driven shaft with an electric motor for driving the driven shaft, with a spring unit that is tensioned during the corresponding opening movement of the door or window and released during the corresponding closing movement of the door or window to provide the closing moment And with a control device for operating the electric motor. Background technique [0003] Such non-hydraulic door or window drives are used to electrically close the flaps of an open door or an open window. This is especially relevant for smoke and f...
