ABSTRACT:
The device according to the invention includes at least one rotational actuator fitted with a return spring and a connecting rod connected to the rotational actuator to transmit a linear movement to a mechanical part. The rotational actuator is moved by a rotational electromagnet whose angular position is controlled by a pulsed, periodic current. The device also includes apparatus for removal of the magnetizing energy stored in the electromagnet.
