Nema 17 Stepper Motors

NEMA 17 – 12V – four-phase unipolar permanent-magnet stepper-motor 1.8° full step – 200 steps-per-revolution 0.9° half-step – 400 steps-per-revolution NEMA chose to label stepper motors (e.g. “NEMA 17”) with the size of their faceplate in tenth of inches. So a “NEMA 17” has a 1.7 inch by 1.7 inch faceplate. By standardizing the stepper […]
