Advisory Message
Pre-sales advice
1. Connect the motor to the controller and power supply according to the wiring diagram on the controller.
2. The tire is installed outside the outer rotor hub.
3. When the power cord passes through metal parts, it should be protected by non-metal products.
4. Special attention: When the motor is powered on by the driver and the motor does not move or freezes, or it heats up abnormally quickly, the power must be turned off and on within three seconds to adjust the electrical angle or drive output to avoid motor failure
