• Bipolar Stepper with 4.25:1 Gearbox (57STH56 NEMA-23)

Description:
This NEMA-23 motor has an integrated Planetary gearbox with a 41/4 :1 ratio. It comes with the rear shaft exposed, so you can mount an encoder or shaft coupler (see recommended items Tab).

When connected to a 1067 - PhidgetStepper Bipolar HC, the 3332 has a maximum speed of 375 RPM. At the output of the gearbox, the step angle is approximately 0.42°. When using the step angle in calculations, you should derive the exact step angle by dividing 1.8° by the gearbox reduction ratio.

At 2.8 Amps, this stepper motor can produce a maximum torque of 46.6 kg-cm. However, the gearbox is only rated for 90 kg-cm of continuous torque. Loading this gearbox stepper beyond the torque rating of the gearbox will shorten its useful life.
