In principle, working
windmills as "Recipient of
Energy", which means he receives
energy (kinetic) from the wind and turn it into another usable
energy such as electricity. The wind that comes will hit the
fan wings (the blades) at
windmills, so that the wings of the
fan will spin..
Then wing
fan will rotate the shaft in the nacelle (tube-shaped rear wing
fan in
windmills). Shaft connected to the gearbox (a kind of toothed wheels), the gearbox shaft rotation speed enhanced with how to set the gear ratio in the gearbox. The gearbox is connected to a generator that will convert mechanical
energy into electrical
energy. Of generators of electrical
energy flowing to the transformer (a device used to raise or lower voltage) to increase the voltage. then electricity can be distributed / distributed to where it is needed.
