Abstract

In a rotary drive for rotating a panel-shaped solar module, rotary pulses with a limited rotational path are introduced from outside only by step. A rotatable gear disk in the rotary drive has a regularly ratcheted control contour with ratchet units like teeth. In cooperation with a control member, what this attains is that the rotatable gear disk returns to a defined stable starting/center position when rotating up to a limiting angle, but when the limiting angle is exceeded advances at least one ratchet unit. The solar module is connected rotation-fast to the gear disk. What this embodiment attains is that the positioning accuracy of the solar module is largely independent of the rotary pulse introduced from outside. This means that a group of rotary drives can be rotated jointly with a central drive via mechanical coupling links, and despite the inaccuracies of a mechanical coupling there is good and uniform positioning accuracy for the individual solar modules.
