This is the motor you want if you are looking for a low cost unipolar stepper that needs to do some work.
This motor must be controlled by a stepper motor controller. 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 connect the motor to a bipolar motor controller, leave out the red wires.
Note: Make sure to unplug the power cord from the controller board before switching wires around.
