Replaced by the 3319_1 - 42STH38-1684A NEMA 17 Bipolar 99.51:1 Planetary Gearbox Stepper.
This NEMA-17 motor has an integrated Planetary gearbox with a 991044/2057 :1 ratio. At 1.6 Amps (maximum current), this gearbox stepper can produce a maximum torque of 250 kg-cm. The gearbox is only rated for 40 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.
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.

The 3319 stepper motor connects to the 1063 - PhidgetStepper Bipolar 1-Motor.
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. |
