3. Configuration et installation

Une installation correcte est essentielle pour les performances et la sécurité du moteur.

3.1 Montage du moteur

The AXI 5320/28 motor typically mounts using the included hardware. Ensure the motor is securely fastened to the airframe's motor mount using appropriate screws. Use thread-locking compound on screws to prevent loosening due to vibration.

3.2 Connexions électriques

Connect the motor to a compatible Electronic Speed Controller (ESC) according to the ESC's instructions. The three motor wires can be connected in any order; if the motor spins in the wrong direction, swap any two of the three wires.

• Assurez-vous que toutes les connexions sont sécurisées et isolées pour éviter les courts-circuits.
• Verify that your ESC is rated for the motor's current draw (65A / 30s peak).
• Use appropriate battery packs (max. 32 Ni-CD or 10s Li-Poly) that can supply the required current.

4. Mode d'emploi

Before operating, ensure all components are correctly installed and secured. Always perform a pre-flight check.

4.1 Sélection de l'hélice

Choosing the correct propeller is vital for efficiency and to prevent motor overload. Refer to the table below for recommended propeller sizes based on aircraft type and battery configuration. Exceeding recommended propeller sizes can lead to overheating and damage.

4.2 Initial Run and Calibration

After installation, perform a low-power test run to confirm correct motor rotation and ESC calibration. Gradually increase throttle to check for smooth operation and unusual noises. Monitor motor temperature during initial flights.

5. Entretien

Regular maintenance ensures the longevity and reliability of your AXI motor.

• Nettoyage: Keep the motor free from dirt, dust, and debris. Use compressed air or a soft brush to clean the motor, especially around the bearings and windings.
• Roulements: The motor's bearings are sealed and generally maintenance-free. However, if you notice excessive noise or play, the bearings may need replacement.
• Inspections : Periodically inspect all wiring for fraying or damage. Check motor mounts and propeller adapters for tightness.
• Température: Avoid operating the motor at excessively high temperatures. If the motor is too hot to touch after a flight, review your propeller choice, battery, or ESC settings.

6. Dépannage

Cette section aborde les problèmes courants que vous pourriez rencontrer.

• Le moteur ne tourne pas :
  • Vérifiez la connexion et le niveau de charge de la batterie.
  • Verify ESC is armed and connected correctly.
  • Inspect motor wires for breaks or loose connections.
  • Ensure propeller is not obstructed.
• Motor spinning in wrong direction:
  • Inversez deux des trois fils du moteur connectés au contrôleur de vitesse électronique (ESC).
• Surchauffe moteur :
  • Propeller may be too large or too aggressive for the motor/battery combination. Refer to the propeller chart.
  • Insufficient airflow for cooling.
  • ESC timing settings may be incorrect (refer to ESC manual).
  • Damaged bearings or internal short.
• Loss of power/intermittent operation:
  • Loose connections between motor, ESC, or battery.
  • Vol batterietage sag or low charge.
  • ESC thermal shutdown or faulty.
