Design and Fabrication of Windmill by Using Maglev Technology

Abstract

Renewable energy is electricity produces from sources, such as wind, solar, geothermal and various forms of biomass. The popularity of renewable energy has experienced with 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. Bases on research, it is estimated that renewable sources might contribute about 20% – 50% to energy consumption in the latter part of the 21st century. Worldwide there is now over two hundred thousand wind turbines operating with a total name plate capacity of 432,000 MW as of end 2015.Unlike the traditional horizontal axis wind turbine, this design is levitated via Maglev (magnetic levitation) vertically on a rotor shaft. It serves as an efficient replacement for ball bearings used on the conventional wind turbine and is usually implemented with permanent magnets. This levitation will be used between the rotating shaft of the turbine blades and the base of the whole wind turbine system. It does not need to vast spaces required by more conventional wind turbines.
