Design analysis of MAGLEV-VAWT with modified magnetic circuit generator

Abstract

This paper presents the design component aspects of a Magnetically levited Vertical Axis Wind Turbine and to report the result analysis using an modified magnetic circuit. The modified magnetic circuit generator reported in our earlier work is tested with the built-in MAGLEV-VAWT. Initially three different wind profiles and the suitable airfoil for the vertical axis wind turbine is derived. The position of the blades to derive maximum velocity is analysed. The degree of impact at angle of 30° is found to have the highest lift coefficient. The structure is then built under laboratory conditions. A modified magnetic circuit generator is used to test the generating capability of the turbine under low speed and high speed conditions. A dual magnetic surface is attached into the structure through an external mechanical structure to reduce the mechanical oscillations. The system is then investigated with and without the maglev structure. It is found that the vibrations are reduced by 37.5%.
