11-5-05 The CNC project will be using bipolar stepper motors. These motors have 200 steps per revolution or 1.8 degrees per step. The ones I have chosen have 276 oz-in of holding power and are based on the NEMA 23 frame size. They will be powered by a transformer that outputs around 40V @ 8A. ![]() Four wire Bipolar motor. ![]() |
