This motor is a larger NEMA-17 motor that produces a whopping 4800g-cm of holding torque. The motor is also very efficient in converting current into torque and velocity.
The 3303 stepper motor connects to a bipolar motor controller such as the 1067 – PhidgetStepper 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.
