Stepper motors take a much different control than brushed or brushless. It has to have pulsed power through pairs of wires in sequence to actually move, so it's something like polarity dependant Blue-yellow, red-black, Blue-yellow, red-black... Get a battery, each time you hit a pole it has the shaft jump a fraction of a turn, hit the next pole another fraction of a turn.

But are you sure you want a stepper? Also it's going to sound like an old printer or a scanner.
