Electromagnetic actuator comprising a frame (1) and an electric motor (2) driving the movement of at least one transmission element (3) connected to the frame via a braking device (6), a magnetic torque limiter (5) and a unidirectional transmission member (4), the braking device comprising an electrical activation member (6.5) in such a way that when the activation member is supplied with power, the unidirectional transmission member is disengaged from the frame and that, when the activation member is not supplied with power, the unidirectional transmission member is engaged with the frame and opposes the pivoting of the transmission element in a direction of rotation up to a maximum transmissible torque defined by the magnetic torque limiter (5). |
