HOBBYWING EZRUN MAX 56118SL G2 Motor Instruction Manual

1. Introduction

This manual provides essential instructions for the proper installation, operation, and maintenance of your HOBBYWING EZRUN MAX 56118SL G2 Motor. Designed for high-speed 1/7th and 1/8th scale RC vehicles, this sensorless brushless motor offers exceptional power and performance. Please read this manual thoroughly before use to ensure safe and optimal performance.

2. Safety Instructions

• Always disconnect the motor from the power source (battery) before performing any maintenance or installation.
• Ensure all connections are secure and properly insulated to prevent short circuits.
• Operate the motor within its specified voltage and current limits to prevent damage.
• Keep hands and loose clothing away from rotating parts during operation.
• Avoid operating the motor in wet conditions unless specifically designed for it.
• Store the motor in a dry, cool place away from direct sunlight and corrosive materials.

3. Product Features

• High-Speed Design: The motor rotor supports a maximum speed of up to 78,000 RPM, suitable for high-speed RC vehicle applications.
• Optimized Pairing: Engineered for seamless compatibility with the EzRun MAX5 HV Plus G2 ESC, enabling higher speeds and greater power output.
• Modular Construction: Features a detachable design for easy cleaning and maintenance, contributing to an extended operational lifespan.
• Exceptional Power: Delivers outstanding power and performance for 1/7th and 1/8th scale RC vehicles.

4. Setup and Installation

Proper installation is crucial for the motor's performance and longevity. Follow these general guidelines:

1. Mounting: Securely mount the motor to your vehicle's motor mount using appropriate screws. Ensure there is no excessive play or misalignment.
2. Pinion Gear Installation: Install the pinion gear onto the motor shaft. Ensure proper gear mesh with the vehicle's spur gear. A small amount of play is necessary to prevent binding.
3. Electrical Connections: Connect the three motor wires to the corresponding ESC (Electronic Speed Controller) wires. For sensorless motors, the order of connection typically does not matter for initial function, but reversing two wires will reverse motor rotation. Ensure connections are soldered securely and insulated.
4. ESC Pairing: For optimal performance, pair this motor with the EzRun MAX5 HV Plus G2 ESC as recommended by Hobbywing. Refer to the ESC manual for specific pairing and calibration procedures.

5. Operating Instructions

Once installed and connected, the motor operates in conjunction with your Electronic Speed Controller (ESC). Ensure your ESC is properly calibrated to the motor and your radio system.

• Initial Test: After installation, perform a low-power test to confirm correct motor rotation and functionality before full-power operation.
• Temperature Monitoring: Regularly monitor motor temperature during operation. Excessive heat can damage the motor. Adjust gearing or driving style if temperatures are consistently high.
• Battery Compatibility: This motor supports 6-12S LiPo cells. Always use batteries that are compatible with both the motor and your ESC.

6. Maintenance

Regular maintenance helps prolong the life and maintain the performance of your motor.

• Cleaning: Periodically clean the motor to remove dirt, dust, and debris. The modular and detachable design facilitates easier cleaning. Use compressed air or a soft brush.
• Inspection: Regularly inspect the motor for any signs of wear, damage, or loose connections. Check the motor shaft for straightness and the bearings for smooth operation.
• Bearing Care: While sealed bearings require minimal maintenance, extreme conditions may necessitate occasional lubrication or replacement.
• Storage: When not in use, store the motor in a clean, dry environment.

7. Troubleshooting

If you encounter issues, consider the following common troubleshooting steps:

• Motor Not Spinning:
  • Check all electrical connections between the motor, ESC, and battery.
  • Ensure the battery is charged and functioning correctly.
  • Verify ESC calibration with the motor and radio.
• Motor Overheating:
  • Reduce the pinion gear size or increase the spur gear size (lower gear ratio).
  • Check for binding in the drivetrain or wheel bearings.
  • Ensure adequate airflow around the motor.
• Reduced Performance:
  • Check battery health and charge level.
  • Inspect motor for physical damage or debris.
  • Verify ESC settings and calibration.
