Abstract

An actuator assembly comprising an output member rotatable about an output axis, first and second actuators each having an axis of rotation, a drive motor and a hold motor, first and second linkages between each of the first and second actuators and the output member, wherein a torque produced by a drive motor is summed through the linkages at the output member when the respective hold motor is restrained from rotating, and wherein the respective hold motor may be selectively released so that it rotates with a failure of the respective drive motor, and wherein one of the first or second actuators may be driven to selectively rotate the output member with a failure of the drive motor of the other of the first or second actuators. The assembly may comprise a third actuator linked to the output member in the same manner as the first and second actuators.
