Abstract
The invention relates to a method for position-controlled stopping of rotating components of shaftless drive mechanisms in the case of voltage loss, whereby the lacking process power arising from a lack of rotational power is supplied by means of an external connectable network.
Claims7
A device for position-controlled stopping of rotating components (01;
- 22) with position-controlled drive mechanisms (02;
- 21) in the case of voltage loss, wherein the rotating component (01;
- 22) is supplied with a required differential energy (ED) that is the difference between the existing rotation energy (ER) of the rotating component (01;
- 22) and the process energy (EP) required for a correctly-positioned stopping of the rotating component (01;
- 22), wherein an external network is provided, which supplies the differential energy (ED), characterized in that the external network (17) has a battery (31).
A device for position-controlled stopping of rotating components (22) with position-controlled drive mechanisms (21) in the case of voltage loss and, through the use of a drive converter (23)—which is at least comprised of a rectifier (24), an intermediate DC circuit (26), a DC-AC converter (27), and a control element (33)—and an uninterruptible energy source (17)—which is at least comprised of a rectifier (24), a DC circuit (26), a DC-AC converter (27), a battery management (29), a battery (31), and a control element (33)—, characterized in that the uninterruptible energy source (17) can be connected to at least the input and output elements (24;
- 27) of the drive converter (23).
