Help - Control linear actuator speed with potentiometer

165

02:38:32

So I have two actuators, both 24 volt. One rated at max 10.5 Amp and the other rated at Max 7.7 Amp
I need to control both of them in regard to speed and direction (in and out).
I found this 10K ohm joystick https://minielektro.dk/mini-analog-joystick-10k-potentiometre.html
So I tried to draw a simple diagram with one 10K ohm pot and a motor... but motor does not turn at all.
In real life, this will be hooked up to two car batteries in series. to have the 24 volt and enough amp.
I know I can use relays to switch the polarity (direction of the actuators).
But with my limited knowledge, I'm stuck in finding a solution to use the joystick which have two potmeters.... should i find one with 4 potmeters, so I have one for each direction?
I had a small potmeter that I tried with... but it burned up in a second

How can a 4-Axis joystick only have 2 potmeters... what am I missing?

Hmm... seems the magic word is PWM ?

The joystick appears to have center zeroed potentiometers. And you are correct, some PWM circuitry with some fairly decent power FETS would be required.

Most pots cantos handle high current the best and most efficient way to power the fans would be with pulse width modulation (pwm)
