Maharashtra, India Abstract This paper presents the design component aspect of a magnetically levitated vertical axis wind turbine. Using the effects of magnetic repulsion, spiral shaped wind turbine blades will be fitted on a rod for stability during rotation and suspended on magnets as a replacement for ball bearings which are normally used on conventional wind turbines. Maglev wind turbines have several advantages over conventional wind turbines. For instance, they’re able to use winds with starting speeds as low as 1.5 meters per second (m/s). Also, they could operate in winds exceeding 40 m/s. This type of wind setup does not require any significant land for installation, as its can be easily incorporated in rooftop, tower, and buildings. The VAWT is defined by an axis perpendicular to the unperturbed flow direction. It is considered that the blades carry their own weight leading to a reinforced root region. During operation the blades experience aerodynamic and inertia forces, which are deflecting the blades outwards, leading to an alternation of the aerodynamic loads. The interplay of load alternation and blade deflection could lead to a diverging flutter motion. After a fitting design is obtained, the blade motion has to be inspected for a safe use during operation.

INTRODUCTION Energy is important for the development of human civilization. As conventional energy exhausts, the development of clean and renewable energy, such as wind and solar becomes ever important to people’s live. The wind power has been harnessed by mankind for a long time and the associated technology is more advanced than other clean energies. Nowadays wind power increasingly attracts interests and its utilization has entered a rapid development stage. Its main advantage is that it uses frictionless bearing and magnetic levitation design and is does not need a vast space required by more conventional wind turbine. It also requires little if any maintenance. Currently the largest conventional wind turbines in the world produce only five megawatts of power. However, one large maglev wind turbine could generate one GW of clean power, enough to supply energy to 750,000 homes. II. MAGNETIC LEVITATION In selecting the vertical axis concept for the wind turbine that is implemented as the power generation portion of this project, certain uniqueness corresponded to it that did not pertain to the other wind turbine designs. The characteristic that set this wind generator apart from the others is that it is fully supported and rotates about a vertical axis. This axis is vertically oriented through the centre of the wind sails, which allows for a different type of rotational support rather than the conventional ball bearing system found in horizontal wind turbines.
