The invention relates to an electro-mechanical actuator with electronic control device meant for rotary actuation of any element or equipment which needs a maximum angular rotation of 180°. According to the invention, the actuator consists of a rotor having one or more permanent magnets (9) with radial magnetization, mounted by means of a bush (18) clamping or adhered onto an axle (8) which is mounted on two bearings (7) each of them integrated into a plate (5, 6) of a material of high magnetic permeability, of windings (3) which are placed about some statoric poles (2), which are located on either side of the magnet/magnets (9) on the rotor and are mounted on some supports (4) of a high permeability material, fixed on the ends of the plates (5, 6) to form together a rigid assembly, of a circular torsion spring (16) mounted about the axle (8) of the rotor, the spring (16) having one end fixed on one of the plates (5, 6) and the other end fixed, through a connection element (13) to the axle (8) of the rotor, and of an electronic device which provides the winding supply and, implicitly, the rotor movement between two standing positions. |
