Frequently asked questions
How do I reverse the motor direction?
Swap the polarity of the two supply wires. Reversing the connections changes the direction of rotation.
Can I run it above its 12V rating?
The rated voltage is 12V. Running at higher voltage increases speed, current and heat, so use a driver and supply that can handle it and keep the motor within its operating temperature range.
