Test Setup for Analysis of Torque on DC Motor Shaft and its Possible Applications

In this paper, we try to use a linear load cell to measure the torque acting on the shaft of a geared DC actuator. With the help of this measured parameter, we are analyzing several possibilities of this model to be used for different application. PID controller is used to making it a closed loop system to reduce the errors, as much as possible. With proper tuning of PID and calibration of the load cell, we can achieve position control without a rotary encoder. We are exploring the possibilities of using minimum sensors to achieve multiple actions to be performed by the actuator.
