Electromagnetic actuator with magnetic torque limiter

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). 种电磁致动器，该致动器包括框架(1)和电动机(2)、磁性扭矩限制器(5)以及单向传递构件(4)，该电动机驱动经由制动装置(6)连接于框架的至少个运动传递元件(3)的运动，该制动装置包括电气激活构件(6.5)，以使得当对激活构件通电时，该单向传递构件从框架脱开，并且当并未对该激活构件通电时，该单向传递构件与该框架接合，并且抵抗该传递元件沿其中个转动方向至高达由该磁性扭矩限制器(5)所限定的最大可传递扭矩的枢转。
