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 mounted on the outside of the outer rotor hub.
3. Power cords passing through metal parts should be protected with non-metallic materials.
4. Special Note: If the motor does not move, jams, or overheats rapidly when the drive powers on the motor, the power must be disconnected and the electrical angle or drive output adjusted within three seconds to avoid motor failure.
