Hisun HS500cc 18 Pole Magneto Rotor

Hisun HS500 18 Pole Flywheel Rotor

For Hisun HS500 4-Stroke Liquid Cooled Engine

18 Pole Magneto Flywheel Rotor · Weak magnetization can cause faulty running · Damaged rotors can cause severe engine damage and noise

This product is an 18-pole flywheel rotor designed for the Hisun HS500 4-stroke liquid cooled engine. It is the core rotating component of the magneto system. The flywheel rotor is mounted on the end of the crankshaft and rotates with it. The permanent magnets inside the rotor create a rotating magnetic field, interacting with the stator coils to generate alternating current, powering the vehicle's electrical system and charging the battery.

⚠️ Important Note: Weak magnetization can cause engine running problems such as poor ignition and insufficient charging; damaged rotors can lead to severe engine damage and abnormal noise. Regular inspection and timely replacement of problematic rotors is essential for proper engine operation.

🔋 Effects of Rotor Failure

• Weak Magnetization: May cause ignition system problems, insufficient charging, dim lighting, unstable engine operation.
• Rotor Damage: May cause scraping with stator, metal debris generation, severe internal engine damage, and abnormal noise.
• Timely Replacement: If rotor problems are detected, replace immediately to avoid more severe engine damage and higher repair costs.

• OEM Matching: Specifically designed for Hisun HS500 engine, ensuring perfect fit and reliable performance.
• Quality Magnets: Made with high-performance permanent magnet materials, providing stable magnetic field strength for reliable power generation and ignition.
• Precision Balanced: Rotor undergoes dynamic balancing test for smooth operation, reducing engine vibration.
• 18-Pole Design: 18-pole rotor provides ample power generation to meet the electrical demands of various vehicle equipment.
• Durable Construction: Made from high-strength materials capable of withstanding high-speed rotational forces, ensuring long-term reliable operation.

✅ Typical Symptoms of Rotor Failure: Battery not charging properly, unstable electrical system operation, dim lighting, hard starting, poor ignition, abnormal engine noise (such as scraping or vibrating sounds). If you experience these symptoms, inspect the flywheel rotor for magnetization weakening or damage.

⚠️ Installation Note: Replacing the flywheel rotor requires removal of the engine side cover and the use of special tools. This operation should be performed by an experienced professional technician. Pay attention to the rotor orientation and position during installation, ensuring alignment with the crankshaft keyway. Use special tools to tighten the rotor mounting bolt to the specified torque. After installation, check the clearance between rotor and stator to ensure no contact. Reconnect the battery and test charging and ignition system functions.
