Features:
1. Design for wind system, wind solar hybrid system, wind solar hybrid street light system.
2. Gear-free design: No need to replace worn-out or broken teeth
3. Brushless: No motor brushes that are high failure items and need replacements regularly
4. Bearing-free design: No need to lubricate or to replace worn-out bearings
5. Floating magnet design: reduces rotational resistance to enhance electricity generation and extend turbine life
6. No yaw or furling mechanism required: allows for peak power output at any wind speed
7. No cogging torque for cutting-in at low wind speed
8. Direct-drive: Extends product life
9. Blades can start rotating at a mere wind velocity of 2.2 mph (1 m/s)
10. Space-saving, aerodynamic airframe,
