An electromechanical actuator (11) for a closure, obscuring or solar protection installation (6) includes a motor assembly (16), including an electric motor (261) and a reduction gearbox (265), first and second (133) mechanical modules for filtering vibrations, and an output shaft (20), inserted at least partially in a casing (17), the electromechanical actuator (11) extends along a longitudinal axis (X), the first and the second mechanical modules (33, 133) being disposed on either side of the motor assembly (16) along the longitudinal axis (X) and each having a rigid transmission coupling, with at least a first degree of freedom perpendicularly to the longitudinal axis (X), allowing the motor assembly (16) to move along a plane perpendicular to the longitudinal axis (X), the electromechanical actuator also comprising at least one elastic module (130) that limits the movement of the motor assembly (16) along the perpendicular plane.
