Abstract

An electricity generator comprises a generator housing 2 connected beneath a bearing hub assembly 4 that is beneath a vertical axis wind turbine 6. A support frame 8 is attached to the bearing hub assembly 4 to secure the generator to a supporting structure such as a wall, chimney or mast. Bearing hub assembly 4 comprises a casing containing plural bearings (fig 3, 58, 62) surrounding a rotatable shaft 26 that is connected to, and driven by rotation of, the turbine. Shaft 26 extends from the bearing hub into the generator housing 2 that contains at least one pair of radial fixed plates (fig 2, 16, 18) having aligned openings through which the rotatable shaft 26 extends and between which are arranged plural coils 28. At least one radial spinner plate (fig 2, 30A, 30B) is fixed to and rotates with the shaft and carries plural magnets (fig 2, 32A) that induce an electrical current in the coils to be conveyed to an external store or electricity consumer by cable 19. The wind turbine can comprise wind vanes 94 mounted on rods (fig 11, 88) that pivot on a pair of axially spaced apart rotor plates 74 mounted on a central column (fig 10, 84) connected to the shaft 26. Pivotal movement of the vanes is limited by pegs (fig 9, 98/100) and biased by spring dampers (fig 9, 102). In light winds the vanes remain closed but in strong winds they can open to provide an escape path for the wind.
