RB-Phi-267

12V, 1.7A, 667oz-in NEMA-23 Bipolar Stepper Motor

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 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.

Motor Controller and Connection

The stepper motor connects to a bipolar motor controller such as the Bipolar HC. 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.
