Title: Servo speed controller swap out
Post by: TheSniper on August 26, 2018, 12:43:47 am

All,
I have a Servo that the speed controller is a S49 Linear hall effect sensor. 
Is it possible to just replace it with a Potentiometer?   10K? wire for wire.?
Basically the controller uses a mechanical foot pedal. and I want to control it with a knob.

I hoe the question is clear enough.
TIA! Sam

Yes, you should be able to replace it with a circuit that contains a potentiometer. You can't just swap it with a potentiometer and get the exact behavior.
Depending on the circuit around it you can design a potentiometer circuit that acts the same as the S49.

You should study the point of signal interface at which kind of signal the hall-effect sensor setup gives the rest of the controller.
