There are two types of systems of electric aerogeneration by using wind turbines, one is called horizontal axis wind turbine (HAWT) and the other one is called vertical axis wind turbine (VAWT). Both of them have advantages and disadvantages depending on many factors. Since the second one had produced lees power than the first one, they were ignored. However, the adaptation of a levitation system and a new system of magnetic induction made VAWT increase the power produced and exceed the HAWT. Although VAWT models were studied enough in the design and experimental scheme, there is no solid explanation, based on basic principles, on the operation of the VAWT. In this paper is proposed a theoretical model of VAWT operation. Therefore, three studies are done: the interaction between wind and blades of the turbine, the magnetic levitation system and the energy production by magnetic induction. Those studies make us able to know and predict the operation of those systems. Since, we shall know how many factors are affecting the efficiency of the system; we shall be able to control those parameters in order to get the best efficiency.
