Build A DIY 800W Axial Flux HAWT
Most wind turbine generators are of the radial design, which means that the flux produced by the magnets flows perpendicular from the rotor shaft through the coils and back. The stator coils are wound around laminated steel cores which attract the flux and helps direct it long distances through the coils and back to the rotor magnets again.
