What force does the drive need to open my window? What stroke length is required to achieve the desired opening angle?
These and similar questions inevitably arise when dealing with the retrofitting of windows and skylights with electric drives. We will show you formulas kindly provided by AUMÜLLER AUMATIC GmbH, Thierhaupten, and perform a few sample calculations.

The following table shows a listing of SKF Magnetic type designations and their successor type at Mingardi. We also provide references to discontinued types and their successors, if any.
It is not uncommon for us to hear in our consultations that the drives are to be installed in bedroom windows that are even to open or close the window in automatic mode during the night. This is just one example of how it makes sense to take a closer look at the issue of noise development.
We explain how chain drives are constructed and why the chain can push...
"Does the drive "fit" or not?
We often receive queries about the type designation of our JM type drives. Therefore, I will give you a short list of the differences here. I do not limit myself to the "ending" in the type designation (i.e. 0, L, LS, LA, ...), but also go into the type code completely.
In most cases, side-hung windows are opened with vertically mounted chain drives. A chain extends and pushes the sash inward or outward. The chain length plays a decisive role here for the maximum opening width (or the opening angle). The opening width corresponds to the chain length, the angle can be calculated:
In order to avoid confusion, I would like to briefly outline what we mean by "skylight". Window professionals may please forgive me if the following information is not entirely correct.
