Performance of Axial Generator for a Small Vertical Axis Wind Turbine

This paper presents an investigation of an axial generator for a small vertical-axis wind turbine.The performance of the axial generator design is tested by knowing the output voltage produced by varying the rotation.The generator is designed to generate three phases of electric power.And then through the wind turbine controller, three phases of alternating current are converted into direct current/DC.The Axial generator uses neodymium permanent magnets with many winding poles of 12 pieces.The coil uses 0.5 mm diameter copper enamel wire with a total of 400 turns each.A voltage of 30 Volt DC is obtained for the rotation of the axial generator at 300 rpm.For application, the generator can be used for a small vertical-axis wind turbine for stand-alone street lighting, which needs only 12 Volt of DC.
