Abstract:
1. A wind power generator comprising: a substantially tubular rotor and a substantially tubular stator, the stator being supportable by a support tower; each of the rotor and the stator carrying one of mutually opposed magnetic field generators and windings; the stator and rotor being substantially concentric such that one of the stator and rotor lies at least partly within the other of the stator and rotor and such that the mutually opposed magnetic field generators and windings face each other; a hub attached to the rotor at an end of the rotor opposite the support tower and supporting at least two blades extending radially therefrom; and a single bearing mounted diametrally between the stator and the rotor such that an inner race of the bearing is carried on a hub end of the inner of the stator and the rotor and an outer race of the bearing is carried on a hub end of the outer of the stator and the rotor, the single bearing handling both thrust and journal loading.
