At certain blade angles, the orientation of the concave side of the blade can significantly improve the efficiency of small vertical wind turbines.
Patent 7967569, specifies the relationship between blade width and the wind wheel diameter ratio, further improving small vertical wind turbine efficiency.
The positive pitch angle regulation is incorporated for over-speed protection when wind speeds exceed the rated wind speed. It can significantly improve the power generation and wind speed range of small wind turbines.
A similar patent together with the above patent 8272840.
The coaxial structure of the wind wheel and generator can significantly improve the stability of the wind wheel rotation and extend the life of all types of vertical wind turbines.
