The project is a small part of a much larger system, and I did not intend to spend so much time trying to get the motor to move as I need.As for the motor itself, the specs state DC phase resistance as 10 ohms and it operates on 3.5V. It is unipolar.I do have a stepper controller board that is based upon an L298 which can handle more current and heat than the H-bridge I am now using.
