I need to sense the torque of a stepper motor at any given time. I'm planning to tension a wire by using a stepper motor, and in order to keep the wire at a fixed tension I would need to know the tension at any given time. Based on this I can turn the stepper motor to achieve the desired torque.
If this is not possible, appreciate some alternatives on how I can achieve this. I've looked into strain sensors as well, but not sure if this works.
