I'm building a device powered by an electric motor, it needs to travel much slower than the RPM output the motor has... I've gotten into some trouble with my circuit trying slow the thing down, hoping for some suggestions... at the moment my circuit goes: battery, switch, potentiometer, motor, (back to battery). - All connected in series. Without the potentiometer there's no problems, but I'm finding the once I put one in it overheats within a few seconds... it's a 12v, 2.3Ah battery dont know the switch's specifications but i havent had any problems with it The motor's specifications I dont know (still in a testing/playing around to see what works phase - I could buy a different motor later if needed)... I took it out of a golf buggy though, so maybe you could make an educated guess about the info you need to help me? :/ sorry... The potentiometer I tried was 3W, 200Ohm... Sooo.... What can I change to make the circuit function better? Any help would be greatly appreciated.
