Dear all,
I am currently working on a numerical model using the data collected from a servo motor. Based on some prior knowledge about the DC motor, the torque is supposed to be proportional to the current. However, to my surprise, the experimental results did not seem to be in line with my hypothesis.
In one of the experiment, the input current is kept constant and the servomotor is used to carry a weight at an equilibrium position. By slowly removing part of the weight, the position does not change at all even though the current remains constant. Does this actually tell that the output torque of the servomotor is not proportional to the input current?
Kindly advice. Thanks!
