Abstract - Savonius wind turbine is the vertical axis wind
Vertical axis wind turbine is the best option for the acquired the wind energy from all the direction. Vertical axis wind turbine has not required any yaw mechanism. It is simple in construction. The Savonius turbine is to be used for this vertical axis wind turbine. The Savonius wind turbine is rotated at the low speed wind turbine is rotated at the low speed wind, due to the minimization of friction between shaft and stator the total wind speed of turbine observed passes to the generator. This causes the Savonius wind mill are rotated at high speed within the low wind speed [1].
turbine. Savonius has the two cu shaped structures. Savonius wind turbine is one of the turbines which are operated in the low speed wind. This produce the high operating torque at the low speed, it is the self-starting turbine. Savonius would use with the magnetic levitation for obtaining the high speed rotation of the generator. Magnetic Levitation is the phenomenon which is anybody is freely suspended in the air without any support with the opposed of gravitational energy. This magnetic levitation occurred due to the repulsion between the two symmetrical poles. The strong levitation is occurred with the used of permanent magnets.
Savonius turbine wind turbine is used with the magnetic levitation for reducing the friction between the rotor and stator. This turbine is worked at the low wind speed. This turbine gives the maximum power than any other wind mill. We are created the design of Savonius turbine with levitation.
Key Words: Savonius Turbine, Magnetic Levitation, Rotor, Generator.
1. INTRODUCTION
1.1 Savonius turbine Now a day, the electricity is generated from conventional energy sources. These sources will be at the end of the scale. For save this sources, we will be must use the renewable energy sources. The wind energy is the one of the big energy source of renewable energy sources. The wind mill are used the wind power for produce the electricity.
The Savonius wind turbine was invited by Finnish Engineer Sigurd Johnson Savonius in 1922.The Savonius turbine is one of the simplest turbines. Aerodynamically, it is a drag-type device, consisting of two or three scoops. When we look from top side it will be appeared as the "S" shape cross section. The drag force turns the Savonius wind turbine. It has the maximum torque at the starting.
Wind is the form of solar energy. Wind is created from the atmosphere of the sun causing areas of uneven heating. In conjunction with the uneven heating of the sun, rotation of the earth and the rockiness of the earth's surface winds are formed. This wind energy strikes on the blade of turbine which rotate the turbine. This rotation of turbine shaft rotates the shaft of generator which is coupled together. The mechanical energy of wind is converted into the electrical energy. The wind mill gas the various bearing, gear mechanism, which absorbs the energy in friction form.
The horizontal axis wind turbine will not be used at household applications. It is difficult to construct. Savonius turbine is the best option for household power generation in the load shading region.[2] This constructed also on the roof floor.
2. THEORY AND DESIGN Power of Wind Turbine
For reducing the friction between the bearing and shaft we are use the magnetic levitation. Magnetic Levitation are suspended the shaft in air without contact with steady side part of wind mill. This totally neglects the Friction between the shaft of rotor and the stator assembly. Due to this, speed of wind power is not reduced and it passes to the generator shaft.

Wind energy is attacked on the blade area with the mass of air flow with kinetic energy. The wind power is defined as the multiplication of mass flow rate and kinetic energy per unit mass.[3] The wind power is given by,
