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. Index Terms—Vertical Axis Wind Turbine, generator I. PROJECT BACKGROUND For conventional generators, there usually used single rotation which is only the rotor will rotate, while the stator will remain static [1], [2]. Single rotating of generator limit the rotation and directly limit the output voltage [2], [3]. Double rotation of axial axis generator was designed to solve this problem. The generator also is known as a multifunction generator due to the rotor can be as a stator and a stator can be as a rotor. Due to this situation, the resulting output produced by this multifunction generator will be higher compared to the output produced by the conventional generator. 978-1-5386-8369-9/18/$31.00 ©2018 IEEE
