I'm getting started with Stepper motors and I got one on ebay, it's MINEBEA NEMA23 2.5V/1.8 AMPS 1.8DEG/STEP (model# 23LM-C045-01H). I'm a bit confused by it's low voltage. Am I reading it correctly, it's 2.5Volts? Stepper driver that I have requires at least 8 Volts (it's Arduino with rugged motor driver shield), so is it safe to drive with motor with voltage of 9 or 12 volts? How would one drive such motor at 2.5VDC?
