Nema 17, 27:1 Planetary Gearbox Stepper Motor DIY CNC Robot Camera
Product Description
This is a short geared NEMA 17 Stepper motor. It has an integrated planetary gearbox with a 26.85 : 1 gear ratio, the resolution reach 0.067° step angle. It's a good solution in applications that need very low rotation speeds and/or lots of torque.
Please note, this planetary gearbox is not high precision gearbox, the backlash we can promised is <=1 degree.
