The potential of wind energy in Indonesia is generally relatively less compared to other countries in the subtropical region. With the Darrieus VAWT Type Vertical Axis Wind Turbine, the turbine does not have to be directed to the wind to be effective. Mill with vertical axis, generator and gearbox can be placed near the ground, so the tower does not need to support it and is more accessible for maintenance purposes. Gearbox is one of the main components of the motor which is referred to as a power transfer system, the transmission functions to move and change the power of the rotating motor. To get a large turbine torque, a gearbox design (large size on the turbine and a smaller size on the rotor generator) is needed. The number of blades used will also affect the effectiveness of the turbine in capturing the wind. With the number of 3 blades, get torque above 40 rpm, at wind speeds of 4.5 to 5 m/s.
