Abstract
This electromechanical actuator configured for controlling screens includes an electronically-commutated, brushless, DC electric motor, a rotor and a stator of the electric motor being positioned coaxially around an axis of rotation, the rotor including a rotor body provided with magnetic elements distributed over the outer surface of the rotor, the magnetic elements of the rotor being surrounded by the stator, the stator being formed by a stator core including a circular peripheral wall and pole elements supporting windings, the pole elements being distributed on the inside of the peripheral wall. The ratio between the outer diameter of the stator and the inner diameter of same is less than 1.7. Further, the ratio between the axial length of the stator and the outer diameter of the stator is greater than 1.5.
