Abstract

1. An electronic blocking device for D.C. motors comprising an element of a position detector (3) connected to the driving shaft (d) of the motor (M) and a driving stage (2) for the motor connected to an amplifier (4), characterized in that, for the feedback control of the motor current to the motor (M), the position detector (3) is connected to a differential amplifier (4) wherein a control current acting in both directions against the applied torque and blocking the position of the driving shaft is transmitted to the motor (M) through the driving stage (2).
