400W 12 / 24V Patented Blade Design Small Wind Turbine For Home
Over-speed Controll System
Smart Blade Aerodynamics Braking and Electromagnetic Speed
This power curve generated by wind tunnel testing indicated that
the blade aerodynamics braking system starts to take effect from
14-15m/s wind speed,the rotor RPM is always limited within wind
turbine rated maximum RPM at even higher wind.
Abandoned the traditional failure-prone mechanical furling
system,the blade itself is designed with over-speed braking system
which will generate a reverse reluctant torque to lower the blade
rotation speed so that the blades and generator can be well
protected in higher wind,it solved safety and reliability problems
facing by most small wind turbines.
Combination of Electromagnetic braking and aerodybamic braking
maximizes energy capture by extend turbine's operating speed range
into higher and lower wind speed which are missed by the old style
