ABSTRACT:
The invention relates to a device for controlling a mechanism driven by at least one electric motor (11, 12), said device comprising a circuit (20, 38) for detecting the power consumption of the mechanism and for comparing the detected value with at least one current threshold, with confirmation during a defined time and a circuit (54) for controlling the stopping of the mechanism for a given time, as a function of the result of said comparison.
Application more particularly to the field of high-capacity or wide-body aircraft, for the generation of pressure in their hydraulic circuits.
