Vertical-axis Wind Turbines

In partnership with Hi-Energy Korea we are able to supply and install vertical-axis wind turbines, developed for environments with mild winds and rapid changes in wind direction. The technology has been widely recognized for its efficiency around the world and has been awarded all needed certifications.

Structure

  • Rotor: Connected joints of blade, central axis of wind turbine.

 

  • Blades: Wings that rotate by the wind. Same structure as the wings of an airplane with lift rotor blades; increases accelerating force through tension and enables abrupt acceleration in wind speed. Delivers power needed for starting the blades of drag force; applicable for various types of winds; convenient to convert to lift force after acceleration through drag force.

 

  • Generator: A device that converts rotations of blade into electrical energy PMG-type Generator (PMG: Permanent Magnet Motor). Even if wind stops blowing, there’s no rolling resistance problem caused by zero load. Therefore, it maintains rotating status for a certain while, boasting high energy resilience when wind starts blowing again.

 

  • Controller: A device for charging/controlling the generated electric energy in (rechargeable) batteries.

 

  • Battery: Gathers the generated electricity to provide power when needed.

Advantages

» High efficiency achieved by acceleration through a sweep-back angle: Even more energy generated under the same wind speed (other products generate energy in proportionate to wind speed)
» Independence over wind direction: Other products generate less energy against a head wind, however, our products generate more energy. Energy conversion is available for any direction of winds.
» Energy generation by gentle winds: Our generator in the form of PMG (Permanent Magnet Motor) has no gear or coil.This permanent magnet motor can be propelled even with light winds unlike other turbine motors.
» Double-blade structure inside and out: Savonius blades are used on the inside for operation by gentle winds, while Darrieus blades are adopted on the outside for achieving high efficiency alongside the inner blades.
» The world’s only product with the benefits of lift force and drag force altogether: Our turbine starts operating by gentle winds and keeps running for a long while even when there’s no load because of its zero rolling resistance. It also boasts of high energy resilience when winds start blowing again.
» Minimized wind resistance: Other turbines, although it is a vertical-axis type, are susceptible to bending and damage, leading to heat error, due to a difference in the area affected by winds. On the contrary, our turbines are designed to circulate the wind flows, minimizing damage and consequent heat error.
» Less noise caused by rotation: Substantially lessens the noise caused by the coating phenomenon and bearing during the rotation of blades, as there is no friction without gear and coil.
» Excellence in maintenance and structural stability: Double-jointed blade structures and anodizing finishing contribute to heightened durability and structural stability of our product.

Types of Vertical-axis Turbines

Tower-type Wind Turbine System

We recommend the tower-type wind turbine when there's need for power generation system of large capacity. Once the blades start rotating, the blades of the adjacent wind turbines automatically start rotating as well, which maximizes not only the spatial applicability but also the generation efficiency. According to the researchers of the California Institute of Technology the dense intervals of vertical-axis wind turbines can save the space needed for installing wind turbines by the hundredths.

Hybrid Streetlight

Hybrid streetlights use both wind power and photovoltaic power to ensure stability in securing energy sources. In addition, all types of wind sources can be converted into electrical energy regardless of its directions. The magnetic method that these streetlights employ eliminate all mechanical noise and ensure effective production of electricity and accelerated generation.

Rooftop Wind Turbine System

Rooftop Wind Turbine System uses upward wind from buildings and is perfect for residential buildings. It utilizes the rising currents of air climbing the sides of a building and the side winds. It can be installed in one or two layers, depending on the power generation capacity, taking into consideration the limit imposed on the rooftop structures.

Protruded Wind Turbine

System based on rising currents of air and the side Winds through the city architecture. Protruded wind turbine system effectively utilizes the rising currents of air climbing the sides of a building and the gushes of winds generated innately from the corners of buildings.
