• Bipolar Stepper with 99.51:1 Gearbox (42STH38 NEMA-17)

Description:
This NEMA-17 motor has an integrated Planetary gearbox with a 991044/2057 :1 ratio.It comes with the rear shaft exposed, so you can mount an encoder or shaft coupler.

When connected to a 1067 - PhidgetStepper Bipolar HC, the 3329 has a maximum speed of 34 RPM. At the output of the gearbox, the step angle is approximately 0.018°. When using the step angle in calculations, you should derive the exact step angle by dividing 1.8° by the gearbox reduction ratio.

At 1.7 Amps, this gearbox stepper can produce a maximum torque of 250 kg-cm. However, the gearbox is only rated for 48 kg-cm of continuous torque, and 100 kg-cm for brief overloads. Loading this gearbox stepper beyond the torque rating of the gearbox will shorten its useful life.
