This NEMA-17 motor has an integrated Planetary gearbox with a 26 103/121 :1 ratio. At 1.68 Amps (maximum current), this gearbox stepper can produce a maximum torque of 77 kg-cm. However, the gearbox is only rated for 30 kg-cm of continuous torque, and 80 kg-cm for brief overloads. Loading this gearbox stepper beyond the torque rating of the gearbox will shorten its useful life.
When connected to a 1067 - PhidgetStepper Bipolar HC, the 3318 has a maximum speed of approximately 174 RPM. At the output of the gearbox, the step angle is a little under 0.07°. When using the step angle in calculations, you should derive the exact step angle by dividing 1.8° by the gearbox reduction ratio.
This particular revision of the 3318 is made by a different manufacturer, but should behave very similarly to the revision 0 version.

The 3318 stepper motor connects to a bipolar motor controller such as the 1067 - PhidgetStepper Bipolar HC.
The following table 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.
Wire Color | Black | Green | Red | Blue |

Board Connector | A | B | C | D |
Note: Make sure to unplug the power cord from the motor controller before switching wires around.

Connecting the motor directly to a power supply will destroy the motor and void the warranty. If you want to check your motor make sure it is connected to a constant current / chopper drive controller. |
