Abstract
A feedback torque limiter device for an actuator having an input shaft, output shaft and gear reduction for transmitting torque from the input shaft to the output shaft comprises an output torque sensor, and input torque limiter and a feedback mechanism. The output torque sensor senses actuator output torque downstream from an actuator gear reduction. The input torque limiter grounds additional torque from the input shaft when engaged. The feedback mechanism engages the input torque limiter when the output torque sensed by the output torque sensor reaches a predetermined value.
