Abstract
An electromechanical actuator for a motor vehicle brake, comprising an electric motor absorbing a nominal rated current (In), a screw-and-nut movement converter including a screw with an axis (AX) extending in a longitudinal direction and a nut supported by the screw, and comprising at least one elastic return member for varying the resistance to forward motion in the longitudinal direction of an element being transferred between the nut and the screw at a predetermined position, in order to modify the nominal rating (In) of the current flowing through the motor while the element is being transferred to the predetermined position.
