Vertical axis wind motor

Claim 1

A wind motor comprising a rotor assembly including a plurality of wind-drivable vanes rotatable on a vertical axis, and an annular wind deflector assembly surrounding the rotor assembly and including a plurality of deflectors oriented to deflect the wind so that for all wind directions a greater wind force is applied to the rotor vanes on one side of its vertical axis than on the other side thereby causing the wind to rotate the rotor assembly about its vertical axis, said rotor assembly including an upper circular plate, a lower circular plate, and a central rotary shaft fixed to said circular plates, said rotor vanes being fixed between said two circular plates, said deflector assembly including an upper annular ring, a lower annular ring, an upper horizontal plate fixed to said upper annular ring, a lower horizontal plate fixed to said lower annular ring, supports carried by said lower annular ring, and a central stationary shaft fixed to said upper and lower horizontal plates and coaxial with said central rotary shaft, said deflectors being fixed between said two rings, the rotor vanes being planar and oriented in the rotor assembly so that their outer ends form equal acute angles to the radial lines passing through the vertical axis of the rotor assembly, the deflectors also being planar and being fixed in the deflector assembly so that their outer ends form equal acute angles, larger than the acute angles of the rotor vanes, to the radial lines passing through the vertical axis of the rotor assembly.
