Electro-mechanical actuators with integrated high resolution wide operating load range

摘要

An electro-mechanical actuator with wide operating range load includes a shaft and a speed summed differential coupled to rotate the shaft. A prime mover is coupled to the speed summed differential and is configured to react to an output torque of the screw shaft. A torsional spring coupled to the speed summed differential by way of a rotary position sensor for detecting the rotation of the screw shaft thereby measuring the output torque of the shaft for control of the prime mover.

1. An electro-mechanical actuator with wide operating range load, comprising:
a screw shaft; a speed summed differential coupled to rotate the screw shaft; a prime mover coupled to the speed summed differential and configured to drive an output torque of the screw shaft; a torsional spring coupled to the speed summed differential by way of a rotary position sensor for detecting the rotation of the screw shaft thereby measuring the output torque of the screw shaft for control of the prime mover; and a controller connected to the rotary position sensor to detect the rotation of the torsional spring to determine the actuator's output load.
