This type of vertical axis wind turbine will generate electricity without using generator or alternator, But by the application of magnetic levitation concept. This wind turbine is designed to sustain all the forces by wind and to keep the wings of the turbine rotating even though there is low wind force. This type of vertical axis wind turbines has three wings which are attached to the rotating shaft. The wings are designed that they accept the wind which comes from any directions. This project contains design and prototype of vertical axis wind turbine. Key words: Vertical axis wind turbine, Wind energy, Magneti levitation and Alternator.

INTRODUCTION Renewable energy is generally electricity supplied from sources, such as wind power, solar power, geothermal energy, hydropower and various forms of biomass. These sources have been coined renewable due to their continuous replenishment and availability for use over and over again. The popularity of renewable energy has experienced a significant upsurge in recent times due to the exhaustion of conventional power generation methods and increasing realization of its adverse effects on the environment. A wind turbine basically draws the kinetic energy from the wind and converts this power to electrical energy by means of a generator. http://www.iaeme.com/IJMET/index.asp 86 editor@iaeme.com Design and Manufacture of Vetrical- Axis Wind Turbine Based on Magnetic Levitation This project focuses on the utilization of wind energy as a renewable source. In the United States alone, wind capacity has grown about 45% to 16.7GW and it continues to grow with the facilitation of new wind projects. The aim of this major qualifying project is to design and implement a magnetically levitated vertical axis wind turbine system that has the ability to operate in both high and low wind speed conditions. Our choice for this model is to showcase its efficiency in varying wind conditions as compared to the traditional horizontal axis wind turbine and contribute to its steady growing popularity for the purpose of mass utilization in the near future as a reliable source of power generation. 2. TYPES OF WIND TURBINES Many types of turbines exist today and their designs are usually inclined towards one of the two categories: horizontal-axis wind turbines (HAWTs) and vertical-axis wind turbines (VAWTs). As the name pertains, each turbine is distinguished by the orientation of their rotor shafts. The former is the more conventional and common type everyone has come to know, while the latter due to its seldom usage and exploitation, is quiet unpopular. 2.1. HAWT The HAWTs usually consist of two or three propeller-like blades attached to a horizontal and mounted on bearings the top of a support tower as seen When the wind blows, the blades of the turbine are set in motion which drives a generator that produces AC electricity. For optimal efficiency, these horizontal turbines are usually made to point into the wind with the aid of a sensor and a servo motor or a wind vane for smaller wind turbine applications. 2.2. VAWT Vertical axis wind turbines are further subdivided into two major types namely the Darrieus model and the Savonius model. With the vertical axis wind turbines, the concept behind their operation is similar to that of the horizontal designs. The major difference is the orientation of the rotors and generator which ar
