Based on a concept of "cost reduction by large rotor and small generator", a kind of small vertical axis wind turbine (VAWT) called a butterfly wind turbine has been developed with rotor diameter of 7 m and five looped blades. One of the features is a mechanical system which can twist each blade of a VAWT by using the centrifugal force acting on the blades in order to prevent over-speeding of the rotor. The over-speed control system is located at the center of the rotor and can keep the rotor almost a constant speed in strong wind. View the paper here.
