The 5 blades horizontal axis wind turbine has a smart blade aerodynamics braking and electromagnetic speed limitation function. Patented aerofoil 5 blades design with true symmetrical and twisted aerodynamic feature which ensures rotor capture maximum power from wind and operates in amazingly low noise and minimal vibration. True symmetrical and balanced aerofoil blade ensure rotor matching with generator perfectly. Large ratio of tip section chord to root section chord and variable chord airfoil blade ensures rotor start-up easily and running smoothly with high torque and RPM at lower wind condition. Aerodynamic blades designed with over-speed braking system to make sure generator well protected in higher wind. Reinforced Glass-Fiber Nylon is using advanced thermoplastic engineering and precision injection molding technology for higher strength, flexibility and reliability. Our wind turbine with minimal vibration and low noise could be mounted on rooftop safely and its operation wonâ??t affect resident.
