FRICTIONLESS WIND TURBINE USING MAGNETIC LEVITATION

Abstract

The paper describes the implementation of different type of a wind turbine for purpose of power generation. A vertical axis wind turbine (VAWT) with use of magnetic levitation technology for optimal performance of wind turbine has been discussed. With the merits of conventional VAWT, the merits of starting at low wind-speed, higher efficiency, low noise emission, etc. are also discussed. The major consequence in front of conventional wind turbine is loss of energy during rotation. By using nature of permanent magnet as a perfect replacement for ball bearings levitation of the turbine is intended thus reducing energy losses while rotation. Using this effect wind turbine blades are placed on a rod for obtaining stability during rotation. Power is then generated by using an axial flux generator, which has incorporated the utilization of permanent magnets and a set of coils.
