An electromechanical actuator to operate a component in an internal combustion engine comprising an actuator body housing, on the inside, an actuator device, which controls the movement of the component so as to move it between a maximum opening position and a maximum closing position, and vice versa. The actuator device includes an electric motor and a gear drive that transmits the motion from the electric motor to the component. The electromechanical actuator is made of a first metal material and comprises a conditioning circuit comprising a pipe for the passage of a conditioning fluid, which is made of a second thermally conductive material. A method of manufacturing the electromagnetic actuator is also disclosed.

A method of manufacturing and controlling a butterfly valve for an internal combustion engine; the manufacturing and control method includes the steps of: establishing a maximum gaseous flow rate value which may flow through the feeding pipe when the butterfly plate is in the closing position; determining a conventional closing position at which the gaseous flow rate which flows through the feeding pipe is essentially equal to the maximum gaseous flow rate value; driving an actuator device so as not to normally pass the conventional closing position; and dimensioning the position of a catch element, so that when a rotational shaft abuts against the catch element the gaseous flow rate which flows through the feeding pipe is essentially lower than the maximum gaseous flow rate value.
