ABSTRACT:
A vertical axle paddle motor including a support structure with a rotor mounted on the vertical axle, the rotor having a plurality of arms with paddle members pivotally attached to the end of the same. Each of the paddle members include a plurality of adjustable vanes which move from an open to a closed position within the paddle. Vane position in the paddles is controlled by a wind velocity and wind direction control, operating a pair of cams forming a composite cam surface which is engaged by cam followers on each of the rotor arms associated separately with motors on the paddle, to adjust the position of the vanes within the paddles for maximum efficiency in rotation. The wind velocity cam may be adjusted relative to the wind direction cam to increase the amount of time the vanes of the paddles are held in an open position to reduce and stabilize rotation of the rotor. The wind velocity cam may also be adjusted by a separate motor means to prevent any of the vanes from moving to a closed position causing cessation of rotor rotation.
