Hi, I've got a little 3 volt DC motor that I'm trying to speed control. I bought 5 potentiometers at Frys ranging from 5K Ohms to 50 k Ohms hoping one would do the job. They can all control the speed, but only within a tiny fraction of their knob travel distance. So the motor sits still until I get to 95% of a knob turn, then I've got speed control in that 5% of knob travel. Sounds like too much resistance, but all the 5 pots I've tried have different resistances and they all behave the same . Can someone clue me in on what pot would give me a greater range of control? Thanks.
