A wind rotor assembly is constructed as a variation of a Savonious rotor with two offset compound curve rotor plate members symetrically located about an axis and including a smaller S-shaped rotor at the axis in the space between the first and second rotor members. The assembly is used singly or in composite assemblies of several rotors on a common shaft, and it produces increased torque and operates at low wind velocity for use in the generation of electricity or in conjunction with a water pump or other applications.

A rotor assembly including in combination: a rotatable shaft; first and second curved side rotor plate members each formed as a section of a cylinder having a radius R1, said plate members each being concentrically located a distance R1 from the axis of said shaft on diametrically opposite sides of said rotatable shaft, each of said first and second rotor plate members having first and second edges parallel to said shaft; third and fourth rotor plate members each formed as identical concave elongated sections and each attached respectively to the diametrically opposite first edges of said first and second rotor plate members at a distance R1 from the axis of said shaft to form discontinuities of curvature in the form of apexes along the lines of attachments thereof, said third and fourth rotor plate members curving toward said shaft and terminating in respective edges thereof parallel to said shaft, spaced less than the distance R1 from the axis of said shaft, and equidistant from a plane defined by the diametrically opposite second edges of said first and second side rotor plate members; and first and second end plate members attached to said first, second, third and fourth rotor plate members and located in spaced parallel planes perpendicular to the axis of said shaft to form end walls for said rotor assembly.
