Patented aerofoil 5 blade design with true symmetrical and twisted aerodynamic design which ensures rotor capture maximum power from wind (Cp>0.35 in low 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 & RPM at lower wind condition

Aerodynamic blades designed with over-speed braking system to make sure generator well protected in higher wind.

Reinforced nylon glass-fiber using advanced thermoplastic engineering and precision injection molding technology for higher strength, fl exibility and reliability.

Smart Blade Aerodynamics Braking and Electromagnetic Speed Limitation

Patented Blade Design Over-speed Control System

HY Small Wind Turbine Special Features

Abandoned the t radi t ional fa i lure-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 aerodynamic braking maximizes energy capture by extending turbine’s operating speed range into higher and lower wind speed which are missed by the old style wind turbines.

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.

Minimal Vibration and Low Noise Operation

Maintenance Free Design

Everything with moving parts will make some noise and vibration, and wind turbines are no exception, most noise and vibration are caused by turbine blades rotation in the wind and generator resonates with rotor and tower, HY Energy well designed wind turbine could works quietly in both low and high wind.

Typical wind turbine has three moving parts(rotor, head yawing and mechanical furling), HY Energy replaced mechanical furling by using advanced electromagnetic and blade aerodynamics braking and take only two moving parts, which improves generator reliability dramatically as it has less mechanical failure.

Wind turbines with typical slip ring design often twists and tangles the connection cable from generator to controller, which made the system has to be maintained every few month. HY Energy patented slip ring design solved this problem completely and made HY wind turbine with higher reliability and real maintenance free.

The blades have exceptional consistency and aerodynamic outline with a mass distribution which ensures the rotor operate with minimal vibration and very low noise.

Perfectly matched rotor and generator cause much less resonance of wind turbine and tower.

Blade Aerodynamics Braking limits blade to rotate at rated RPM which could avoid higher noise and vibration caused by extreme wind.

Wind turbine with minimal vibration and low noise could be mounted on rooftop safely and its operation won’t affect resident.

Innovative two-moving-part system

Innovative slip ring design

Best Material and Workmanship

Patented rotor is made of high quality stainless steel rotor shaft attached with permanent neodymium magnet, the unique winding and multi pole design reduces the start-up torque of alternator which assures generator would produce more power at lower wind condition than other system.

Rotor and housing

Generator housing is made of precisely casted aluminum alloy with minimal tolerance and sealed with high quality sealant, this is why HY wind turbine could work normally under various working conditions, and this is why HY wind generator features class B insulation and IP56 class protection. Besides, HY generator system is designed with a suffi cient buffer of overload to ensure overall wind turbine reliability.

Blades are made from reinforced nylon glass-fi ber by using advanced thermoplastic engineering and precision injection molding technology for higher strength, fl exibility and reliability.

HY Wind Turbine Structure and Special Features

Power output chart

With HY R&D team efforts and years of technology accumulation and fine workmanship, HY wind 6th generation wind turbines proved an excellent performance, durability and reliability, following generator efficiency testing result shows what HY turbine is capable of and we expect you could start to test our wind turbine yourself. Results speak themselves!

Wind – shows power in the wind watt per square meter

BETZ limit – shows the theoretical maximum power could be captured from wind

Max produced – shows maximum power a wind generator could generate from wind

5 blades HY-400 power curve shows excellent power output performance at lower wind speed, and the blades aerodynamics braking system starts to protect wind turbine from 14-15m/s wind speed

Typical 3 blades wind turbine generates lower power at low wind speed and no protection for wind turbine at higher wind speed, wind turbine may break down if dump loader doesn’t work properly.

HY 5 blades wind turbine shows excellent wind power utilizing efficiency at lower wind (more than 40%), and also good performance at higher wind because smart blade aerodynamic braking could limit rotor speed within its rated RPM to keep generating power in higher wind.

Typical 3 blades wind turbine captures much less power from wind at lower wind speed, and wind power effi ciency drops in higher wind because dump loader or mechanical furling braking system intermittently limits rotor speed in constantly changing wind, which results in average effi ciency drop.
