Description
NEMA-17 bipolar 4-wire with integrated planetary gearbox
Holding torque: 30 kg·cm
Gear ratio: 26 103⁄121:1
Rated current: 1.7 A
The 12V, 1.7A, 416 oz-in Geared Bipolar Stepper Motor has an integrated Planetary gearbox with a 26 103/121 :1 ratio. It comes with the rear shaft exposed, so you can mount an encoder or shaft coupler. At 1.7 Amps (maximum current), this stepper motor can produce a maximum torque of 77 kg-cm. However, the gearbox is only rated for 30 kg-cm of continuous torque, and 80 kg-cm for brief overloads. Loading this gearbox stepper beyond the torque rating of the gearbox will shorten its useful life.

NEMA-17 bipolar 4-wire
Rear shaft exposed for compatibility with encoders
Note: The 2.8V refers to the phase voltage which is different than the 12V rating we give it. At the end of the day, stepper motors don't have a "Rated Voltage" per se. You can run them at a wide range of different voltages and it will just change the performance of the motor. We recommend that you use this motor at a minimum of 12V but you could run it at 24, or 30 if you wanted to and the motor would simply perform a bit better (require less current for a given speed and torque).
Precise, high torque, useful for inertial navigation
I tried these motors after difficulties with plain DC motors (mostly insufficient torque and poor encoder response). Together with EiBotBoard controllers from another supplier, these geared stepper motors made a very positive difference for my project -- the motors have enough torque that stepping never fails, and consequently my robot can now travel tens of meters using pure inertial navigation, and the position error is below 10 cm! :)

Awesome!
I'm using this to directly drive a heavy box. This motor has got a lot of torque. Perfect. Using with a TB6600 driver off the Arduino.

Très puissant
Très puissant et fonctionne très bien avec A4988 pour le prix ça vos le coût et ça fait le travail d'un gros moteur

Awesome motor!
Works well, has a pretty high torque, and not too slow.

Powerful and precise motor
This motor has loads of torque yet can be smoothly driven over a very wide range of speeds, including micro-stepping. Well made and very affordable.
