This NEMA-11 motor has a 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 3322 has a maximum speed 35 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 0.67 Amps, this stepper motor can produce a maximum torque of 60 kg-cm. However, the gearbox is only rated for 32 kg-cm of continuous torque. Loading this gearbox stepper beyond the torque rating of the gearbox will shorten its useful life.

The following diagram shows how to connect the motor wires to the board connectors to produce a clockwise rotation in the stepper motor when increasing position. To wire for counter-clockwise rotation when increasing position, reverse the red and blue wires.

Note: Make sure to unplug the power cord from the motor controller before switching wires around.
