4. Safety Information
Always prioritize safety when working with electrical components. Failure to follow these guidelines may result in injury or damage to the product.
- Ensure the power source is disconnected before performing any installation, wiring, or maintenance.
- Verify that the voltage of your battery and motor matches the controller's specifications (48V/60V/64V).
- Avoid short circuits by ensuring all connections are secure and properly insulated.
- Do not expose the controller to water, excessive moisture, or extreme temperatures.
- Seek professional assistance if you are unsure about any wiring or installation steps.
5. Setup and Installation
Proper installation is crucial for the optimal performance and longevity of your motor controller. Refer to the wiring diagram and video for guidance.
5.1 Wiring Diagram Overview

5.2 Connection Steps
- Power Supply: Connect the main power wires (thick red for positive, thick black for negative) to your battery.
- Motor Phase Lines: Connect the three thick motor phase wires (typically blue, green, yellow) from the controller to the corresponding motor phase wires.
- Hall Sensor Wires (if applicable): Connect the Hall sensor wires (usually a small 5-wire connector) from the controller to the motor's Hall sensor port. If your motor does not have Hall sensors, the controller can operate in 'no Hall' mode.
- Electric Door Lock: Connect the electric door lock wire (often red) to the ignition switch or main power switch. This acts as the ignition for the controller.
- Speed Control Handle (Throttle): Connect the throttle wires (typically a 3-wire connector) to your throttle unit.
- Brake Lines: Connect the low-level brake line and high-level brake line to your brake levers. These provide regenerative braking or motor cut-off functions.
- Three-Speed Lines: Connect these wires to your three-speed switch (if equipped) to select different speed modes.
- General Instrument Line: Connect to your display or instrument panel for speed, battery level, etc.
- Anti-Theft Alarm: Connect the anti-theft alarm power cord and signal lines to your alarm system (if equipped).
- Reverse Gear: Connect the reverse line to a switch for reverse functionality (if desired).
- Intelligent Self-Learning Recognition: After all connections are made, connect the two 'Learning Wire' connectors (often white or black with labels). The motor will spin automatically. Once it runs smoothly, disconnect the learning wires. This process allows the controller to automatically identify the motor's phase and Hall sensor configuration.

6. Operating Instructions
Once the controller is correctly installed and the self-learning process is complete, you can operate your electric vehicle.
- Power On: Turn on the electric door lock or main power switch. The system should initialize.
- Throttle Control: Gently twist the throttle to accelerate. The controller provides smooth acceleration.
- Speed Modes: If equipped with a three-speed switch, use it to cycle through different speed settings (e.g., low, medium, high).
- Braking: Apply the brake levers to engage the braking function. The controller will cut power to the motor and may engage regenerative braking if supported.
- Reverse Function: If the reverse line is connected to a switch, activate it to engage reverse motion.
7. Maintenance
Regular maintenance helps ensure the longevity and reliable performance of your motor controller.
- Keep Clean: Periodically clean the exterior of the controller to prevent dust and debris buildup, which can affect heat dissipation.
- Check Connections: Regularly inspect all wiring connections for tightness and signs of corrosion or damage. Secure any loose connections.
- Avoid Overheating: Ensure the controller is mounted in a location with adequate airflow to prevent overheating, especially during prolonged high-power usage.
- Protect from Elements: Shield the controller from direct exposure to rain, snow, and extreme sunlight.
8. Troubleshooting
If you encounter issues with your motor controller, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Motor does not start | No power, loose connections, electric door lock not engaged, learning wires not used. | Check battery connection, ensure electric door lock is on, verify all main wires are secure, perform self-learning process. |
| Motor runs intermittently or with jerks | Loose Hall sensor wires, incorrect phase connection, motor or controller fault. | Check Hall sensor connections, re-perform self-learning, inspect motor for damage. |
| No response from throttle | Throttle wires loose or damaged, throttle unit faulty. | Inspect throttle wiring, test throttle unit if possible. |
| Controller overheats | Insufficient ventilation, motor drawing too much current, prolonged heavy load. | Ensure adequate airflow around the controller, reduce continuous heavy loads, check motor for issues. |
If the problem persists after attempting these solutions, please contact customer support.
