Frequently asked questions
Can I run it from a 14.4V battery?
The listing says it can replace a 14.4V drill motor, but its rated voltage is 12V. Running above rated voltage increases speed and heat, so check the load and cooling before operating at higher voltage.
What driver do I need for this motor?
Use a switch or motor driver rated for at least the motor's current. The no-load current is 1.2A, and the current under load will be higher.
