4. Asennus ja asennus
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: Päävirtalähde akusta.
- Lukko: Sytytyskytkimen liitäntä.
- Alarm Power Supply / Alarm Wire: For security system integration.
- Study Wire: Used for initial motor learning/pairing.
- Sali: Hall sensor connections from the motor.
- Risteily: For cruise control functionality.
- High Brake / Low Brake: Connections for brake levers (high or low electrical level).
- Käänteinen: For reverse gear functionality.
- Instruments / LCD Display: Connections for dashboard display or LCD panel.
- Throttle: Connects to the throttle grip.
- Kolme nopeutta: For multi-speed selection.
Asennusvaiheet:
- Kiinnitä ohjain: 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.
- Kytke moottorin johdot: Connect the three thick motor phase wires from the controller to the corresponding motor phase wires.
- Hall-anturin johtojen kytkeminen: Connect the smaller Hall sensor wires from the controller to the motor's Hall sensor wires.
- Liitä akkuvirta: 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.
- Kytke kaasuvipu: Attach the throttle wire to the throttle grip.
- Kytke jarruvivut: Connect the High Brake and/or Low Brake wires to your brake levers.
- Liitä tarvikkeet: 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.
- Tarkista yhteydet: Double-check all connections for tightness and correct placement before applying power.
5. Käyttöohjeet
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.
- Virta päälle: Turn the ignition key (if connected) or activate the main power switch. The controller will perform a self-check.
- Kaasun säädin: Gently twist the throttle grip to accelerate. The controller's sensitive response ensures smooth acceleration and deceleration.
- Jarrutus: 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-tilainen toiminta: 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. Huolto
To ensure the longevity and optimal performance of your WFLNHB motor controller, follow these general maintenance guidelines:
- Säännöllinen tarkastus: Periodically check all wiring connections for tightness and signs of wear or corrosion. Ensure no wires are pinched or exposed.
- Puhtaus: 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.
- Lämmön hajoaminen: Ensure the controller's mounting location allows for adequate airflow to its aluminum casing. Do not obstruct the heat dissipation fins.
- Ympäristönsuojelu: Protect the controller from direct exposure to rain, snow, or extreme humidity.
- Akun kunto: Maintain your battery according to its manufacturer's instructions. A healthy battery contributes to stable controller operation.
