## Questions & Answers

**Q: Why does my electric dc motor turn in the wrong direction and slowly?**
A: Check whether the phase wires and Hall wires are properly connected, disconnect the self-learning wire and connect again, let the motor self-study 10 to 20 seconds, then disconnect it, there is no need to connect it after motor rotates normally.

**Q: Why did the motor suddenly stop spinning after it started？**
A: The controller and motor power are large, so the one-time output current of your battery is too large, which turns on the self-protection. Charge your battery for a few minutes and it will be ready for normal use
