I need to control (speed and direction) of a 1.5HP 12v DC motor. If my calculations are correct, I need a 100A motor controller -- and that leaves very little service factor.
I'm looking at these type Controllers on Amazon
Has anyone used one of these?
Is there any reason I couldn't cut the Potentiometer out of this and just apply a PWM signal from an Arduino?
I am pretty sure I could remove the "knob pot" and put in a "digital potentiometer," but I wanted to skip that and just send the PWM into the controller rather then the "pot" voltage." Would that work? or do I need to just plan on using a "Digiat Potentiometer?"
I have experience with the Digital pot on 3-phase VFD's, so I can do it using them.
I have some I use to control 3-phase AC motor VFD's,
