• Protecció integrada: Inclou baix volumtage cut-off protection, overheat protection, and throttle signal loss protection.
• Transmissió de senyal estable: The throttle signal cable utilizes a twisted pair design, effectively reducing crosstalk during signal transmission for more stable flight.

3. Especificacions

Figure 1: RUIZHI 40A ESC with key dimensions indicated. The overall length is approximately 76mm, width 37mm, and height 8mm. The battery wires are about 97mm long, motor wires 85mm, and the signal wire 250mm.

4. Configuració

Proper setup is crucial for the safe and efficient operation of your ESC. Follow these general steps:

1. Connexió del motor: Connect the three motor wires from the ESC to the three wires of your brushless motor. The order of connection may affect motor rotation direction. If the motor spins in the wrong direction, swap any two of the three motor wires.
2. Connexió del receptor/controlador de vol: Connect the signal cable (usually a three-wire servo connector: signal, positive, negative) from the ESC to the throttle channel of your RC receiver or flight controller. Ensure correct polarity.
3. Connexió de la bateria: Connect the battery connector (red for positive, black for negative) from the ESC to your LiPo battery. Ensure correct polarity to prevent damage.
4. Throttle Calibration (Recommended):
   • Turn on your RC transmitter and set the throttle stick to its maximum position.
   • Connect the battery to the ESC. The ESC will emit a series of beeps.
   • Once the beeps indicate the maximum throttle has been recognized, move the throttle stick to its minimum position.
   • The ESC will emit another series of beeps, confirming the minimum throttle has been set.
   • Disconnect and reconnect the battery to complete the calibration.

5. Instruccions de funcionament

After successful setup and calibration, follow these guidelines for operation:

1. Comprovació prèvia al vol: Always perform a pre-flight check to ensure all connections are secure, the battery is charged, and the motor responds correctly to throttle input.
2. Engegada inicial: Connect the battery to the ESC. The ESC will initialize and emit a series of beeps. Wait for the initialization sequence to complete before operating.
3. Control de l'accelerador: Gradually increase the throttle stick on your transmitter to control motor speed. Avoid sudden, rapid throttle changes, especially during initial flights.
4. Seguiment: Pay attention to any unusual sounds or smells from the ESC or motor during operation. If anything seems abnormal, immediately cut power.
5. Postoperació: After use, disconnect the battery from the ESC first. Allow the ESC and motor to cool down before handling.

6. Manteniment

The RUIZHI 40A ESC is designed for durability, but proper maintenance can extend its lifespan:

• Mantenir net: Regularly inspect the ESC for dirt, dust, or debris. Clean gently with a soft brush or compressed air. Avoid using liquids.
• Inspeccionar connexions: Periodically check all wire connections for signs of wear, corrosion, or loose contacts. Ensure solder joints are solid.
• Gestió de la temperatura: Ensure adequate airflow around the ESC during operation to prevent overheating. Avoid enclosing it in tight spaces without ventilation.
• Emmagatzematge: Store the ESC in a dry, cool environment away from direct sunlight and extreme temperatures when not in use.

7. Solució De Problemes

If you encounter issues with your RUIZHI 40A ESC, consider the following:

• El motor no gira:
  • Check all wire connections (motor, battery, receiver).
  • Assegureu-vos que la bateria estigui carregada.
  • Verify throttle calibration.
  • Confirm the motor is not jammed or damaged.
• Erratic Motor Behavior:
  • Torneu a calibrar el rang de l'accelerador.
  • Check for interference with the signal cable.
  • Inspect motor wires for loose connections or damage.
• Sobreescalfament de l'ESC:
  • Ensure proper ventilation around the ESC.
  • Check if the motor is drawing excessive current (e.g., due to an oversized propeller or mechanical binding).
  • Comproveu el volum de la bateriatage is within the 2-4S LiPo range.
• Sense alimentació/indicador LED apagat:
  • Check battery connection and battery charge.
  • Inspeccioneu si hi ha algun dany visible a l'ESC o als cables.

8. Informació de seguretat

Operating RC electronics requires adherence to safety precautions:

• Seguretat de la bateria: Always use LiPo batteries safely. Do not overcharge, over-discharge, or puncture them. Store in a fire-safe location.
• Seguretat de l'hèlix: Always remove propellers from motors before performing any setup, calibration, or maintenance to prevent accidental injury.
• Polaritat correcta: Ensure all connections, especially battery connections, are made with correct polarity (positive to positive, negative to negative). Incorrect polarity can cause severe damage to the ESC and battery.
• Aïllament: Ensure all exposed wires and solder joints are properly insulated to prevent short circuits.
• Medi ambient: Operate RC models in open areas, away from people, animals, and obstacles.
• Aigua i humitat: Mantingueu l'ESC allunyat de l'aigua i la humitat, tret que estigui específicament classificat com a impermeable.
