3. Nastavení a instalace
Proper installation is crucial for the motor's performance and safety.
3.1 Montáž motoru
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 Elektrické připojení
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.
- Ujistěte se, že všechny spoje jsou bezpečné a izolované, aby se zabránilo zkratům.
- 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. Návod k obsluze
Before operating, ensure all components are correctly installed and secured. Always perform a pre-flight check.
4.1 Propeller Selection
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. Údržba
Regular maintenance ensures the longevity and reliability of your AXI motor.
- Čištění: 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.
- Ložiska: The motor's bearings are sealed and generally maintenance-free. However, if you notice excessive noise or play, the bearings may need replacement.
- Inspekce: Periodically inspect all wiring for fraying or damage. Check motor mounts and propeller adapters for tightness.
- Teplota: 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. Řešení problémů
Tato část se zabývá běžnými problémy, se kterými se můžete setkat.
- Motor se netočí:
- Zkontrolujte připojení baterie a úroveň nabití.
- Verify ESC is armed and connected correctly.
- Inspect motor wires for breaks or loose connections.
- Ensure propeller is not obstructed.
- Motor se otáčí špatným směrem:
- Prohoďte libovolné dva ze tří vodičů motoru připojených k ESC.
- Přehřátí motoru:
- 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.
- Baterie voltage sag or low charge.
- ESC thermal shutdown or faulty.
