Abstract

Bei einer Antriebsvorrichtung zur Fernsteuerung der Verstellbewegungen eines Bühnenscheinwerfers, bei der das zu betätigende mit dem Scheinwerfer verbundene Ver­ stellorgan mittels eines elektrischen Motors drehbar ist, bei dem durch ein an das Verstellorgan gekoppeltes Rück­ meldepotentiometer ein Ist-Wert über die tatsächliche Win­ kellage des Verstellorgans erzeugbar ist und bei dem eine Regelschaltung zum Vergleich des Ist-Werts mit einem an der Regelschaltung einstellbaren Soll-Wert vorgesehen ist, wobei der Motor durch die Regelschaltung in der Weise steuerbar ist, dass sich der Ist-Wert dem Soll-Wert stetig annähert und wobei der Motor angehalten wird, wenn der Ist-Wert dem Soll-Wert gleich ist, wird vorgeschlagen, dass als Motor ein getriebeloser Motor (10, 75) vorgesehen ist, dessen Abtrieb über einen Flachriemenantrieb (15, 16, 17; 76, 77, 78), gegebenenfalls einen Zahnriemenantrieb (23, 24, 25), und ein Schneckengetriebe (26, 29, 31; 79, 90, 91) an das Verstellorgan (2, 6, 96) gekoppelt ist, und dass das Rückmeldepotentiometer (36, 83) über einen weiteren Zahnriemenantrieb (31, 34, 35; 80, 81, 82) mit dem Ver­ stellorgan verbunden ist. In a drive device for remote control of the Adjustment movements of a stage spotlight in which the operated Ver connected to the headlight actuator is rotatable by means of an electric motor, at by a back coupled to the adjusting member signal potentiometer an actual value over the actual win kellage of the adjusting member can be generated and one Control circuit for comparing the actual value with an on the control circuit is provided with an adjustable target value, the motor through the control circuit in the way It is controllable that the actual value is continuously the target value approximates and the engine is stopped when the Actual value is equal to the target value, it is proposed that a gearless motor (10, 75) is provided as the motor, its output via a flat belt drive (15, 16, 17; 76, 77, 78), optionally a toothed belt drive (23, 24, 25), and a worm gear (26, 29, 31; 79, 90, 91) is coupled to the adjusting member (2, 6, 96), and that the Feedback potentiometer (36, 83) via another Toothed belt drive (31, 34, 35; 80, 81, 82) with the Ver actuator is connected.
