Abstract
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.
