Wind motors with rotation axis substantially perpendicular to the air flow entering the rotor having stationary wind-guiding means, e.g. with shrouds or channels {having shield means on one side of the rotor orientable with respect to the rotor and only with concentrating action, i.e. only increasing the airflow speed into the rotor }
