Control arrangement of a ac motors blinds or a ac-tube motors

摘要

Control arrangement (1) of a ac motors jalousie or a ac-tube motors (2) with electronic switching on and off, wherein to a first winding (3) of the ac motors jalousie or of the ac-tube motors (2) is an ac voltage via a first line (8) for a first direction of rotation (‘ on ") of the ac motors jalousie or of the ac-tube motors (2) can be applied, and wherein a second winding (4) an ac voltage via a second line (9) for a second direction of rotation (‘ down ") of the ac motors jalousie or of the ac-tube motors (2) can be applied, characterized in that between the ac motor jalousie or the ac-tubular motor (2) and the neutral conductor, an on-off switch (6) is arranged, and in that a control unit (7) for the on-off switch (6) is provided which, from the phase shift between the measured voltages at the first and on the second line (8, 9) during a brief current pulse, which by means of the ignition of the circuit breaker (6) is effected, the selected direction of rotation is determined, and the switching on of the circuit breaker (6) when the ac motor jalousie or the ac-tubular motor (2) is in the end position with respect to the determined direction of rotation is.
