Abstract: A wind power generator has a nacelle; a hub rotatable about an axis of rotation with respect to the nacelle; at least two blades fitted to the hub; an electric machine which is fitted to the nacelle, is bounded by an inner surface extending about the axis of rotation, and has a rotor and a stator; and a cooling system for airflow cooling the electric machine, and which has a deflector body for defining a gap between the deflector body and the electric machine and guiding the airflow into the gap.
