Electromagnetic field configurations for bladeless wind turbines

Abstract

This paper proposes different electromagnetic field configurations for Bladeless Wind Turbines. Unlike the rotatory wind turbines, bladeless wind turbines depend on vibration to generate electrical power. The eXisting bladeless wind turbines use permanent magnets in the electromechanical system used for converting vibration into electrical power. The use of permanent magnets not only makes the system costly but also limits the flexibility of changing the field magnitude and direction. In this paper, an electromagnetic field arrangement suitable for bladeless wind turbines is proposed. Various field coil configurations are presented and analysed using ANSYS®Maxwel The results are compared and the best possible field coil configuration is proposed.
