The present invention relates to a rotor driven by wind power with a vertical rotating axis and radial arms distributed at uniform angular intervals over its periphery which bear bodies with an aerodynamic profile such that one side of the profile exhibits a lower air resistance with a current at right angles than with a current from the opposite side. Known vertical rotors should be of simple construction and should be capable of being manufactured at low cost. At the same time their efficiency should be high enough for them to be used to generate wind power economically. To this end, the rotor of the generic type is improved such that the rotor arms consist of one or a plurality of loops in vertical planes with an aerodynamic profile, where the profile shape is maintained essentially uniform over the entire length of the loop.

Rotor driven by wind power with a vertical rotating axis and radial rotor arms mounted thereon which are distributed at uniform angular intervals over a periphery thereof and which form and bear rotor arms with an aerodynamic profile such that one side of the profile exhibits a lower air resistance

Rotor driven by wind power with a vertical rotating axis and radial rotor arms mounted thereon which are distributed at uniform angular intervals over a periphery thereof and which form and bear rotor arms with an aerodynamic profile such that one side of the profile exhibits a lower air resistance with a current at right angles than with a current from the opposite side wherein the rotor arms consist of at least one loop lying in vertical planes with aerodynamic profiles, where the profile shape is substantially constant over the entire length of the loop, wherein said loops consist of arms diverging at an angle from the region of the vertical rotating axis or the region of a hub attached thereto, said loops having radial outer zones connected with each other by circular arc-shaped profile strips, and several nested profile loops sharing the same arms and formed by inner loops having circular arc-shaped profile strips disposed closer to the rotating axis than outer loops thereof.
