An electric actuator includes a casing having a base, on which an electric motor is fixed having a stator with radially extending straight teeth and having a plurality of coils and a rotor formed by a plurality of magnets. The coils extend in a plane parallel to the base of the casing and the rotor is extended by a pinion forming a worm gear with an axis perpendicular to the orientation of the coils. The worm gear meshes with a threaded rod extending parallel to the base of the casing, wherein the threaded rod is guided at the rear by a fixed smooth bearing or by a fixed nut, with the smooth bearing or nut being rigidly connected to a cover of the casing. The axial end of the worm gear is guided by the cover and a printed circuit, to which the plurality of coils is connected, is positioned between the stator and the threaded rod.

An electric actuator includes a threaded rod turned by a motor, the threaded rod having a drive zone extended on each side by threaded zones, one of the threaded zones collaborating with a stationary nut and the other of the threaded zones collaborating with a nut secured to a control member capable of translational movement along an axis parallel to the axis of the threaded zone, the threaded rod being moved with a helical motion.
