5. Installation Guide
Proper installation is crucial for the safe and effective operation of your electric bicycle or scooter. If you are not confident in your ability to perform the installation, please consult a qualified technician.
5.1 Pre-Installation Checklist
- Ensure the vehicle's power is OFF and the battery is disconnected.
- Gather necessary tools (e.g., screwdrivers, wire cutters/strippers, electrical tape, zip ties).
- Identify the location for mounting the controller, ensuring it is protected from moisture and physical damage.
5.2 Wiring Instructions
The controller features a multi-wire harness. Carefully match each connector to its corresponding component. Refer to the typical wiring diagram below for guidance.
- Power Wires (Thick Red/Black): Connect the thick red wire to the positive (+) terminal of your battery and the thick black wire to the negative (-) terminal.
- Motor Wires (Thick Yellow/Green/Blue): Connect these to the corresponding phase wires of your brushless motor.
- Hall Sensor Wires (Thin Red/Black/Yellow/Green/Blue): Connect these to the motor's Hall sensor wires. Ensure correct color matching.
- Throttle Wires (Red/Green/Black): Connect to your throttle unit. Red for +5V, Green for signal, Black for ground.
- Brake Lever Wires (Yellow/Black or similar): Connect to your brake levers. These typically cut power to the motor when brakes are applied.
- Self-Learning Wires (White/White or similar): These are used for initial motor phase matching. Connect them, turn on power, and the motor will spin. If it spins backward, disconnect and reconnect. Once the motor runs smoothly forward, disconnect these wires.
- Display/Meter Wires (if applicable): Connect to your display unit for speed, battery level, etc. (Specific colors vary by display type).
- Pedal Assist Sensor (PAS) Wires (if applicable): Connect to your PAS sensor for pedal-assisted riding.
After all connections are made, secure the controller in its designated location using appropriate fasteners or zip ties. Ensure all connections are tight and insulated to prevent short circuits.
6. Operation
Once the controller is correctly installed and all connections are secure:
- Reconnect the battery power.
- Turn on the vehicle's main power switch (if equipped).
- Engage the throttle gently to test motor response.
- Test the brake cut-off function by applying the brakes while gently engaging the throttle. The motor should stop.
- If a display is connected, verify that it shows correct information.
The controller automatically detects 36V or 48V battery voltage and 60° or 120° motor phase angle, simplifying setup.
7. Maintenance
The JEARTYIEST 350W Brushless DC Motor Controller is designed for durability and requires minimal maintenance.
- Regular Inspection: Periodically check all wire connections for tightness and signs of wear or corrosion.
- Cleaning: Keep the controller's exterior clean and free of dust and debris. Use a dry cloth for cleaning. Do not use water or solvents.
- Protection: Ensure the controller remains protected from direct water exposure and excessive heat.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Motor does not run | No power, loose connections, faulty throttle, faulty motor, brake engaged. | Check battery connection, ensure main power is on, inspect all wiring, test throttle, check brake lever switch. Use self-learning wires if motor phase is incorrect. |
| Motor runs intermittently | Loose connections, damaged wires, Hall sensor issue. | Inspect all wiring for damage or loose connections. Check Hall sensor wires. |
| Motor runs backward (after initial setup) | Incorrect phase matching during self-learning. | Reconnect the self-learning wires, power on, let it spin, then disconnect and reconnect the self-learning wires. It should then spin forward. Disconnect them once correct. |
| Controller gets hot | Overload, poor ventilation, short circuit. | Reduce load, ensure controller has adequate airflow, check for short circuits in motor or wiring. |
