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