Abstract

A wind turbine axial flux generator for converting wind into electricity includes: a generator rotor which is rotatable about an axis; and a stator; wherein one of the generator rotor and the stator is provided with magnets and the other is provided with electrical windings in which electricity is induced by relative movement between the generator rotor and the stator; and wherein the generator further includes: an up-wind air gap on the up-wind side of the electrical windings, between the electrical windings and at least some of the magnets on the up-wind side of the electrical windings; a down-wind air gap on the down-wind side of the electrical windings, between the electrical windings and at least some of the magnets on the down-wind side of the electrical windings; and at least one wind guide for directing the wind so that the wind flows through both the up-wind air gap and the down-wind air gap in order to cool the electrical windings from both the up-wind and down-wind sides of the electrical windings.
