A drive device for variable load, in particular for lifting devices, of the type that includes at least two asynchronous ring motors, mechanically coupled, characterized in that there are switching means that allow, at will, to feed at least one of the motors with alternating current, in a manner appropriate to their direction of rotation and braking this motor causing the stator to be powered by at least one other motor with rectified alternating current, said alternating current being taken in the rotor rings. Of this same engine. (Machine-translation by Google Translate, not legally binding)
