Frequently asked questions
Which driver should I use with this motor?
Use a driver that supports at least 1.7 A per phase, such as a TB6600 set to 1.7 A or lower. Drivers rated below 1.7 A per phase will not deliver full torque.
How do I wire the four leads?
Connect the coil pairs to the driver's A+, A-, B+ and B- outputs. If the motor turns in the wrong direction or vibrates, swap the two wires of one coil.
