Description:
This NEMA-23 motor has an integrated Planetary gearbox with a 76 49/64 :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 3333 has a
maximum speed of 116 RPM. At the output of the gearbox, the step angle
is approximately 0.12°. 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 960
kg-cm. However, the gearbox is only rated for 240 kg-cm of continuous
torque. Loading this gearbox stepper beyond the torque rating of the
gearbox will shorten its useful life.
