<p>A driving motor (1) for an actuating drive having improved jamming protection of a closing part, e.g., a window pane (2) of a motor vehicle. The closing part is adjusted via a transmission, e.g., a cable drive drum (3, 4). To avoid over-dimensioning of the driving motor (1), a variable transmission is provided that delivers a substantially constant load on the driving motor (1) over the entire adjustment path of the window pane (2). Thereby, a design of the driving motor (1) to cope with an increased load, which would otherwise be caused when the closing part slides into a closed position, is avoided. In addition, since the closing part approaches the closed position with a lower speed, the closing part is able to brake rapidly, if necessary. This results, e.g., in an improved jamming protection function of the closing part.</p> |
