Description:
This NEMA-17 motor has an integrated Planetary gearbox with a 13²¹²/₂₈₉ :1 ratio. At 1.7 Amps, this stepper motor can produce a maximum torque of 49 kg-cm. However, the gearbox is only rated for 30 kg-cm of continuous torque. Loading this gearbox stepper beyond the torque rating of the gearbox will shorten its useful life. It comes with the rear shaft exposed, so you can mount an encoder or shaft encoder (see related items).

When connected to the PhidgetStepper HC (1067) the 3326 has a maximum speed of 295 RPM. At the output of the gearbox, the step angle is approximately 0.13°. When using the step angle in calculations, you should derive the exact step angle by dividing 1.8° by the gearbox reduction ratio.
