Savonius rotor

Savoniův rotor uses the energy of the wind on a different principle than the propeller. It has other characteristics, the more favorable especially in low wind. In the book is described in detail the construction of the facilities and especially all the possible applications, such as pumping water, the production of compressed air, but mainly to the production of electric current. In detail, are discussed all types of generators ac and dc current, with excitation permanent magnet and continuous winding supplied by an external source. For all the structural variants are in tables and graphs demonstrated operational characteristics. Building instructions are accompanied by detailed drawings and diagrams. The obtained performance is up to 1 kW.
