A vertical wind turbine includes an upstanding 3 feet support structure, the top cover contains magnets carefully placed in a specific geometric pattern that generates a rotational force. The cover also has openings to allow for vertical air flow through the structure. Another set of permanent magnets are placed below the rotor shaft for magnetic levitation, resulting in near friction-free rotation. It has a total of 6 airfoils, 3 primary horizontal blades and 3 secondary vertical aerodynamic airfoils in 45 degree angle, thus increasing the total efficiency of wind capture. In summary MagnoWind is a small wind turbine operating on low wind speeds. It utilizes strong permanent magnets strategically aligned to maximize spinning momentum. The magnets counterbalance the weight of the spinning body while minimizing the needed wind force to generate power.
A set of permanent magnet rings (part 3) are used to counteract the weight of added mass in the rotating shaft to optimize spinning momentum, i.e. to keep the turbine spinning longer when wind force is reduced.
The main wing holders are themselves air-foils capturing vertical directed wind, in addition to the primary horizontal wind captured by the main blades.
The main thrust of this patent lies in using the magnetic technology in an efficient way. Rather than using traditional bearing technology, magnetic technology is efficient in supporting and centering the rotating shaft as well as increase the force making the turbine rotate.
