Product Description
- High-grade Neodymium Iron Boron permanent magnets
- Each magnet tested for magnetic flux by authorized institutions
- Engineered for low starting torque requirements
- High generating efficiency through optimized internal structure
- Robust construction for long-term reliability
- Precision-made steel wheel hub
- Blade connectors made from Q235 plate
- Anti-corrosion surface treatment
- Durable performance in harsh environments
- Optimized for reliable blade connection
General Design Features
-Type:Three-phase AC Permanent Magnet Synchronous Generator (PMSG).
- Structure:Outer rotor design (preferred) to allow direct connection to the turbine rotor, providing smooth rotation.
- Excitation: High-grade Rare Earth Magnets (e.g., NdFeB) for high efficiency and no external excitation current required.
- Torque Characteristics: Ultra-low cogging torque (coreless designs can achieve near-zero start-up torque) to ensure generation starts in light breeze conditions (as low as 2.5 m/s).
Key Parameter Descriptions
Electrical Parameters
- Output Voltage:The generator outputs raw three-phase AC. This is typically rectified to DC (e.g., 48V, 96V, 220V, or 380V DC) by the charge controller for battery charging or grid connection.
- Frequency: Variable frequency, proportional to the rotor speed (e.g., 0–50 Hz).
- Efficiency: Typically >90% at rated load for PMSG designs.
