Abstract:
1. 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 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.
