Patent ID: 7391128

Claim:
A wind generator system comprising: a stationary frame having an axis; a first shaft disposed along the axis and coupled to one or more fan blades, the fan blades adapted to receive a wind force such that the first shaft radially rotates about the axis, wherein: (a) the stationary frame comprises at least one magnetic source and the first shaft comprises a highly magnetically permeable material; and (b) the stationary frame and the first shaft are positioned to provide at least one annular gap between a surface of the at least one magnetic source and an opposing surface of the highly magnetically permeable material across which a magnetic field imparts a magnetic attractive force on the shaft in a first direction opposing gravity, a second direction with gravity, and in a third direction opposing the wind force; a first set of mechanical bearings coupled to the first shaft and the stationary frame for allowing radial rotation of the first shaft about the axis relative to the stationary frame and for axially aligning the first shaft and the stationary frame, wherein the first shaft and the one or more fan blades are configured to exert against the set of mechanical bearings a load in the direction of gravity and a load in the direction opposing gravity; a stator coupled to the stationary frame; and a rotor coupled to a second shaft and opposing the stator, the rotor configured to radially rotate about the axis relative to the stationary frame and generate electricity when the second shaft radially rotates about the axis, wherein the second shaft is disposed along the axis and operably coupled to the first shaft via a gear transmission, the gear transmission transferring kinetic energy from the first shaft to radially rotate the second shaft in response to rotation of the first shaft.
