I REALLY wouldn't recommend using a brushed DC motor in an area with acetone vapor. Brushed motors can create small sparks as they run, even a little 3V unit like that. I would suggest using a brushless motor, and have all possible sources of spark (switches, plugs, etc.) as far from the container as possible.

What is your power source for this project?

It's depends of the motor that you have. My motor requires 3V, so I connect it to PC power supply (orange and black wires - it's 3.3V)
