The diameter of the larger wind-rotor is 8 feet [2.4 m]. The smaller machine has 4' diameter [1.2 m]. The diameter is the width of the circular area swept by the blades. The energy produced by wind turbines depends on the swept area more than it does on the alternator maximum output. Alternator The plans describe how to build a permanent magnet

Design and Development of Small Wind Turbines 263 can be put into three categories: rotor aerodynamics, rotor overspeed control, and rotor manufacturing considerations. 1.2.1 Rotor aerodynamics In the early days of grid-connected wind turbines, rotors were usually "stall-con-trolled", i.e. maximum power was limited via aerodynamic stall.

Abstract—This paper presents the design and analysis of vertical axis Savonius wind turbine to generate electrical energy from wind energy. The Savonius rotor was designed with the rotor diameter of 2 m and the rotor height of 4 m. The 3D model of Savonius rotor blade was made by utilizing SolidWorks software.
