I see... my motor controllers have some current limiting built in, but it may not be enough, as applying power to the brush and approaching a stop will cause excessive current on a small part of the potentiometer.
Another way would be to have a potentiometer which cannot reach the absolute limit, so always has a minimum resistance of say 500 ohms. I believe other autopilot rudder feedback are like this.
I am prototyping 3d printed angular hall-effect sensors for rudder feedback to avoid wear out, as well as being completely waterproof, and these seem to not be damaged by connecting the wires in the wrong way.
