Low Wind Speed High Utilization Coreless Permanent Magnet Generator with Ultra-Low Start Torque for Efficient Energy Harvest

Maximizing Energy Harvest in Light Wind Conditions

Specifically optimized for low wind speed environments, this coreless permanent magnet generator achieves remarkably high wind energy utilization through ultra-low start torque technology and efficient magnetic circuit design. Ideal for locations with average wind speeds below 5 m/s.

• Ultra-Low Start Torque <0.1N.M: No hysteresis and gear notches effect enables startup in light wind conditions as low as 1.5 m/s
• High Wind Utilization Ratio: Optimized electromagnetic design captures more energy across the full wind spectrum
• Coreless Stator: Zero cogging torque allows smooth rotation even in minimal wind
• Multi-Pole Rare Earth Rotor: Generates usable power at very low RPM (100-150 RPM rated)
• Gearless Direct Drive: Eliminates mechanical resistance typically found in geared systems

• Extended daily power generation hours — captures early morning and late evening light winds
• Higher annual energy yield compared to conventional generators in same location
• Enables wind power deployment in previously unviable low-wind regions
• Reduced cut-in speed increases utilization factor and ROI
• Compatible with both vertical and horizontal axis wind turbine configurations

• "Precise Coil" technology for optimal low-speed electromagnetic performance
• Aluminum alloy outer frame provides excellent heat dissipation
• Brush-less, maintenance-free design for long-term unattended operation
• 8 times longer lifespan than traditional wound-field generators
