The Savonius rotor is a type of vertical axis wind turbines, characterized by its comparatively massive and drag-driven design.
Savonius rotors are known as drag-type rotors because the entire rotor surface offers resistance to the wind and is essentially pushed away by the wind. However, drag also limits the speed and power of the rotor.
Savonius rotors can only rotate as fast as the wind, and they have the lowest efficiency among all small wind turbines. This means that they produce much less electricity than other designs.
