Abstract

The present invention relates to a device (30) for controlling at least one no‑current brake (11) with which a rotor is equipped, comprising a regulating system for bringing the brake (11) by controlling the supply of power thereto, in to a state reducing the frictional torque applied, so as to allow the rotor to slip and be driven under the effect of a load, the regulation taking place at least as a function of feedback indicative of the speed of the load so as to keep the speed of the load below a predefined threshold.
