Abstract

A device for controlling an electromechanical regulator, including a controller (3a) that controls the current through a coil (113) and which, for that purpose, generates control signals for a power regulator (5a). The control signals are determined with the coil (113) operating in the free-running operating state. The control signals depend, during the movement of the armature, on the current and the time differential of the current through the coil (113).
