5KW Variable Pitch Wind turbine

Product Characteristics

1. Rotation speed controlled by centrifugal force with passive variable pitch mechanism.

2. Power curve optimized by two-stage springs to balance pitch driving force.

3. No tailvane, down-wind design with electricity transmitted by cellecting ring.

4. 3-phase direct drive permanent magnet generator with maintenance free.

5. All surfaces sealed with turbine outer parts pot galvanized,antirust.

6. Quick installation and easy opearating.

7. Compact structure with streamline and nice appearance.

8. Running stability and safety with more than15 years lifetime,easy maintenance.

Variable Pitch Mechanism

Blade angle is positive 15 degree as factory setting at which the turbine is easy to start spinning.

After the turbine getting running ,the angle of blades turns to 0 degree quickly, and the blade acts

at its most efficient point (one spring acts). It outputs 5kW electrical power at 10.5m/s wind speed

with 240 rpm rotor rotation speed. If the wind speed increases,the blade is forced to turn towards

negative angle by centrifugal hammers to limit rotation speed (two springs act). The springs

balance the blades angle and rotation speed while regulating power generating.
