Abstract
Improvements in devices for automatically stopping an electric drive device of the type employing an electrically adjustable coupling connected between a continuously running drive motor and the driven element, and an electrically controlled brake, especially for sewing machines, with means for stopping the actuation in a predetermined position, the coupled coupling being regulated as an electromagnetic friction coupling and the brake through one or several transistors, and connection means to actuate to stop the drive as well as the fixing connection member from the stop position which they are located in the control circuit and the coupling and brake excitation coils that are directly in the working circuit of the transistors, characterized in that the regulating transistor of the brake excitation when switching off is regulated, on the one hand, by a tension of m it is activated depending on the position of a piece of the machine and additionally by a control voltage produced depending on the residual velocity so that the speed-dependent control voltage produces a brief continuation of the drive to a constant residual velocity until the position-dependent control voltage causes the brake to act via a transistor and thus for the drive.
