Abstract
The main aim of the paper is to design a windmill that operates without generator and ball bearings and to get maximum power output. The use of wind energy for energy generation is one of the oldest methods for harnessing renewable energy. Use of renewable energy is an essential ingredient of socio-economic development and economic growth. A vertical axis wind turbine (VAWT) is introduced by magnetic levitation technology to optimize the performance. The system utilizes the nature of permanent magnet as a replacement for ball bearings to levitate the turbine component and thus minimize energy losses while rotating, which is the major problem that furthermore, the system can be suited by conventional wind turbine. The Maglev Wind Turbine is expected to bring wind power technology to the next level. Furthermore, the system can be suited in use for more rural and urban areas of low speed regions. The selection of magnet materials in the design of wind turbine system will be discussed. Power will then be generated with an axial flux generator, which incorporates the use of permanent magnets and a set of coils.
Highlights
The maglev power generation introduces structure and principle of the proposed magnetic levitation wind turbine for better utilisation of wind energy
Magnetic levitation (Maglev) Wind Turbine: The vertically oriented blades of the wind turbine are suspended in the air above the base of the machine by using permanent magnet which produces magnetic force to lift up the blades
The wind energy rotates the wind turbine blades which are fixed to disc and to which magnets are fixed and magnetic flux of these magnets links with the coil which is placed on the base of the maglev wind mill
Summary
The maglev power generation introduces structure and principle of the proposed magnetic levitation wind turbine for better utilisation of wind energy. Maglev wind turbine has the features of no mechanical contact, no friction etc., minimizing the damping in the magnetic levitation wind turbine, which enables the wind turbine to start up with low speed wind and work with breeze. Magnetic levitation (Maglev) is integrated into the turbine system in order to increase the efficiency. If the efficiency of the wind turbine is increased, more power is generated decreasing the need for expensive power generators that cause pollution
