VAWT application example analysis Supposition that the time of average wind velocity is 6m/s is more long than that of

4000h/year in some lace of brain . The operating point of windmill design fixed wind speed is 12m/s, Windmill rotational speed is 50~60rpm, Design requirements that when the wind speed is 6m/s, the permanent-magnet generator's rotational speed is 25~30rpm., when the output is 2KW, the efficiency Eta is 90%,the invertor's transfer efficiency Phi is 95%.

Some farm user wants to gain actual wind electric power 2KW, then he needs to purchase how big the wind turbine and the generator are? Simultaneously, he can obtain the corresponding investment repayment by the shortest time.

VAWT INNOVATION

THE PRINCIPLE OF MAGLEV TRAIN Maglev trains are high-tech vehicle by the use of magnetic attraction and repulsion. Simply, repulsion makes train suspension and attraction makes train running. Maglev trains are equipped with superconducting magnets and the bottom of the railway installed with magnetized coils. After electrified, the magnetic polarity produced by magnetized coil keep consistent with train magnet; According to “ homo-polarity mutually exclusive” , repulsion is produced and makes the train suspension. Different from the momentum of conventional trains, the power of maglev trains does not come from locomotive but tracks. Coils are installed on both sides of tracks, and AC changes them into electromagnet, which interacts with magnet on the train. When the train running, the magnet (N polarity) in the locomotive is attracted by the electromagnet(S polarity) in front of the tracks and pushed by the magnet (N polarity)behind. As a result, the train goes forward due to the front pull and the behind push. When the train arrives at a certain place, the current in the coil reverses flow. The result is the original S coil become N one, and vice versa.

MAGLEV VERTICAL AXIS WIND TURBINE Maglev makes the VAWT with much smaller friction, more efficient and longer life! The problem the traditional structure of VAWT of is the weight from the VAWT makes bearings bear larger axial force, makes bearings frayed largely and shorten the life. At the same time, due to the increase in friction, the system loss mechanical energy and reduce the efficiency. Maglev VAWT use the attracted gather of disc stator and permanent magnetic rotor, in other words, use the attracted gather of magnetic core and the permanent magnet, which makes the bearing overcome axial force and reduce bearing's attrition and lengthen bearing's service life. At the same time, reduce bearing's frictional force, improve the mechanical efficiency.

THE COMMONNESS OF MAGLEV VAWT AND TRAIN IN TECHNOLOGY

AND ENERGY CONSUMPTION The speed and energy consumption of maglev train Maglev trains are running on the track, track and locomotive does not exist any actual touch, that means a “ no wheel" status, and therefore almost no friction between the wheel and track, and its speed can come to 400-550 kilometers per hour. The Difference of Magnetic Principle Magnetic suction is 500 times greater than magnetic repulsion

THE PRINCIPLES OF VARIABLE-WING LEAVES The traditional structure of VAWT blades are made up by the main wing, aileron, and the front aero part, the described aileron is set up at the both sides of the main wing. The main wing, left and right aileron and front aero part are formed integration. The existed problems as below: because the left and the right aileron are fixed, the resistance of the blade area is very big, which will impact the speed of VAWT running.

For our variable-wing leaves on the new VAWT, when the front part against the wind, the left and right aileron will close to the main wing and the resistance is reduced. But when the front part down the wind, the left and the right aileron will away from the main wings and get driving force from the other side of the wind. So you can see the principle of the new VAWT: fully use of the wind energy.
