I've got this electric motor from a K'NEX toy kit I found lying around. It was power by 2 AA batteries (~3V DC). I would like top use this motor on a 12V car circuit, but when I wire it to 12V, it spins way too fast. How can I reduce the voltage significantly? I want it very very slow, possibly slow enough so it will take 5 seconds for the motor to make 1 revolution. I tried using a 470ohm resistor, but then the motor wouldn't even spin. Any ideas?
