All,
I am desparately trying to gain a better understanding of DC circuits of all types, but especially motor control circuits. Any all inclusive resources for this purpose would be greatly appreciated. my specific question at the moment is related to the use of potentiometers in in PWM circuits. I have a 2.5 hp dc motor and controller scavenged from a treadmill. I had a 4.7k pot laying around, so I tied that into the HLW taps on the board. I have control of the motor speed, but not a lot of resolution. What effect would a different size pot have? WOuld a 10k pot give me more resolution, ie finer speed control?
