Abstract
An axial flux synchronous generator for wind turbine generators is provided including a shaft coupled to receive power with a power generating apparatus for the wind turbine; a rotor coupled rotatably to the shaft and having upper and lower disk-like faces affixed with a plurality of skewed permanent magnets having north-south (N-S) pole pairs and distantly arranged; an upper stator and a lower stator both having a plurality of slots formed similar to the skewed permanent magnets for taking windings of a coil, the upper stator being displaced relative to the lower stator by an electric angle in the range of 25˜30°; an upper housing and a lower housing for housing the rotor, the upper stator and the lower stator together; and a hub housing for fastening the upper housing and the lower housing to maintain constant gaps between the rotor and the upper stator and the lower stator.
