Frequently asked questions
What are the wire colors and how do I connect them?
Black is A+, green is A-, red is B+ and blue is B-. Connect the A pair to the driver's A output and the B pair to the B output.
What driver current should I use with this motor?
Use a bipolar driver that can supply 4.4A per phase, and set the current to match the motor and your application. Setting a lower current reduces heating but also reduces available torque.
