This NEMA-17 motor has an integrated Planetary gearbox with a 26.8:1 ratio. At 2.5 Amps (maximum current), this gearbox stepper can produce a maximum torque of 128 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.

The 3312 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.
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.|
