NEMA17 Stepper Motor (40mm)
Stepper motors draw power to hold their current position even if they are not turning, so they tend to be power-hungry. They are best suited for being driven off a power supply rather than batteries unless you are using batteries with some serious current capability.
Bipolar stepper motors require two full H-Bridges to drive them unlike unipolar steppers so they are best paired with a good bipolar driver to drive them. These drivers have active current limiting built-in and allow for the motors to be driven from voltages much higher than their rated voltage (2V in this case) which gives improved performance. What is important in these motors is to not exceed their maximum current capability (1.2A in this case), but you can run them at 12V or higher without any problems.
