12V, 1.7A, 416 oz-in Geared Bipolar Stepper Motor

• 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.

Features

• High Torque
• 0.067° step angle
• 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).
