Basically, wind turbines capture wind power and convert it into electricity. Conventional operation using a single set of rotating blades of the wind turbine, thus it will limit the rotation of the generator's stator. This condition will cause the generated output voltage is limited. The purpose of this project is to design and develop a double rotational generator with a double rotational vertical axis wind turbine that has the ability to produce double output voltages and functional in both high and low wind speed condition. Therefore, a certain shape and size of the blade are divided efficiently designed for this project. The output voltages generated by cutting the magnetic flux generator which combines the use of permanent magnets and a set of winding. The project performance was analyzed based on the effect of wind speed on the output voltages that induced by cutting magnetic flux.
