Since Korea has many mountainous regions, terrains adjacent to the ocean, and it is in a periodic climate zone influenced by monsoons, the wind direction changes from region to region, so wind turbines installed in Korea are continuously and stable regardless of the sudden change of wind direction. It is necessary to have a structure capable of performing energy conversion.

Such wind turbine generators are roughly classified into propeller-type horizontal shaft wind turbines whose rotation axis is horizontal with respect to the direction of the wind, and vertical shaft wind turbines such as gyro mill and Darius whose rotation shafts are perpendicular to the direction of the wind.

However, the conventional wind power generator has a problem that the constant rotational force is not transmitted to the generator because the rotational force of the turbine from time to time varies according to the wind speed. In other words, in the region where the wind direction changes frequently and the wind speed is low, the turbine is not rotated properly, and it is difficult to produce continuous and stable power. When the wind does not occur at all, the power is not produced at all. There was a problem that could make a big hit.

In addition, the conventional wind power generator has only a simple wind direction tracking function, and does not have a separate structure for inducing rotational deflection of the wind and reducing rotational resistance, and thus there is a limit in maximizing the power generation efficiency of the turbine.
