Stepper motor - NEMA-17 - 0.9°/degree.
Brand: Product Code:
  • A stepper motor to satisfy all your robotics needs! This 4-wire bipolar stepper has 0.9° per step for smooth motion and a nice holding torque. The motor was specified to have a max current of 1.7A so that it could be driven easily with a Ramps 1.4 Shield (or other motor driver) and a wall adapter or lead-acid battery. 

    Some nice details include a ready-to-go cable and a machined drive shaft (so you can easily attach stuff). We drove it with an Ramps 1.4 Shield  and it hummed along nicely . To connect to our shield, put the wires in this order: Red, Yellow, skip ground, Green, Brown (or Gray) If you need assistance just drop us a mail or call us and we'll be ever-ready to assist you!

    • 200 steps per revolution, 0.9 degrees
    • Coil #1: Red & Yellow wire pair. Coil #2 Green & Brown/Gray wire pair. (may vary)
    • Bipolar stepper, requires 2 full H-bridges!
    • 4-wire, 12 inch leads
    • 42mm/1.65" square body
    • 31mm/1.22" square mounting holes, 3mm metric screws (M3)
    • 5mm diameter drive shaft, 24mm long, with a machined flat
    • 12V - 3.06V rated voltage (you can drive it at a lower voltage, but the torque will drop) at 1.7A max current
    • 28 oz*in, 40 N*cm, 4 Kg*cm holding torque per phase
    • 35 ohms per winding
