4. Настройка і ўстаноўка
Careful wiring is crucial for the correct and safe operation of the motor controller. Refer to the detailed wiring diagram below and ensure each connection is made accurately.

Image 4.1: Comprehensive wiring diagram illustrating the connections for the motor controller. Key connections include:
- Motor Line: Connects to the motor phases (typically three thick wires).
- Positive Electrode / Negative Electrode: Main power input from the battery.
- Блакаванне: Ignition switch connection.
- Alarm Power Supply / Alarm Wire: For security system integration.
- Study Wire: Used for initial motor learning/pairing.
- Зала: Hall sensor connections from the motor.
- Круіз: For cruise control functionality.
- High Brake / Low Brake: Connections for brake levers (high or low electrical level).
- Рэверс: For reverse gear functionality.
- Instruments / LCD Display: Connections for dashboard display or LCD panel.
- Дросель: Connects to the throttle grip.
- Three Speed: For multi-speed selection.
Этапы ўстаноўкі:
- Устанавіце кантролер: Securely mount the controller in a location that is protected from direct impact, water, and excessive heat, allowing for adequate airflow around its aluminum casing.
- Падлучыце правады рухавіка: Connect the three thick motor phase wires from the controller to the corresponding motor phase wires.
- Connect Hall Sensor Wires: Connect the smaller Hall sensor wires from the controller to the motor's Hall sensor wires.
- Connect Battery Power: Connect the main positive and negative power wires from the controller to your 48-72V battery, ensuring correct polarity.
- Connect Ignition Lock: Connect the ignition lock wire. The controller will only power on when this circuit is closed.
- Connect Throttle: Attach the throttle wire to the throttle grip.
- Connect Brake Levers: Connect the High Brake and/or Low Brake wires to your brake levers.
- Падключыце аксэсуары: Connect any additional accessories such as the LCD display, instruments, alarm system, cruise control, or three-speed switch as per the diagram.
- Perform Study Wire Pairing (if applicable): Some controllers require a 'study wire' connection to automatically identify motor parameters. Follow specific instructions for your motor if this feature is present.
- Праверка злучэнняў: Double-check all connections for tightness and correct placement before applying power.
5. Інструкцыя па эксплуатацыі
Once properly installed, the WFLNHB motor controller provides sensitive and efficient control over your brushless DC motor. This controller supports a 2-mode operation, allowing for flexible power delivery.
- Уключэнне: Turn the ignition key (if connected) or activate the main power switch. The controller will perform a self-check.
- Кіраванне дросельнай засланкай: Gently twist the throttle grip to accelerate. The controller's sensitive response ensures smooth acceleration and deceleration.
- тармажэнне: Engaging the brake levers will cut power to the motor, providing a safe stop. The controller supports both high and low electrical level brake signals.
- 2 рэжымы працы: The controller is designed with a 2-mode function, which typically refers to dual-mode control (e.g., Hall sensor mode and sensorless mode). This allows for continued operation even if Hall sensors fail, or provides optimized performance under different conditions. Consult your motor's specifications for optimal mode utilization.
- Speed Selection (if connected): If a three-speed switch is connected, use it to select your desired speed mode (e.g., low, medium, high).
6. Тэхнічнае абслугоўванне
To ensure the longevity and optimal performance of your WFLNHB motor controller, follow these general maintenance guidelines:
- Рэгулярны агляд: Periodically check all wiring connections for tightness and signs of wear or corrosion. Ensure no wires are pinched or exposed.
- Чысціня: Keep the controller free from dust, dirt, and debris. Use a dry, soft cloth to wipe down the exterior. Do not use liquid cleaners directly on the controller.
- Цеплааддача: Ensure the controller's mounting location allows for adequate airflow to its aluminum casing. Do not obstruct the heat dissipation fins.
- Ахова навакольнага асяроддзя: Protect the controller from direct exposure to rain, snow, or extreme humidity.
- Зарад батарэі: Maintain your battery according to its manufacturer's instructions. A healthy battery contributes to stable controller operation.
