Abstract
AbstractA small scale vertical axis wind turbine (VAWT) withaxial flux permanent magnet (AFPM) generator has beendesigned and magnetic levitation method is used toincrease the efficiency of this type of wind turbine [1].Magnetic levitation is inserted by using rare earthpermanent magnets, the repelling force of magnets areused to suspend the rotating part of both turbine andgenerator. Moreover, design of simple generator whichcan easily drive without geared mechanism, lessen costand the complexity of the system by reducing thequantity of driving components. Three phase output isobtained from designed generator which is converted intodirect current through three-phase rectifier to charge thebatteries. The performance of proposed prototype is alsotested experimentally. The turbine performs as predictedby the design process.
