How Small Wind Turbines work
The Small Wind Turbines are upwind, horizontal-axis wind machines where the rotor spins in front of the tower about a line parallel with the horizon. It comprises of following main components:
- A propeller (also termed as windmill) made out of aerodynamically shaped rotating blades mounted on a shaft.
- An Alternator or Generator for producing the electricity when the shaft is rotated.
- A Tail or Vane at the back of the wind turbine is used to steer it into or out of the wind automatically.
- A well anchored, robust and tall Tower for mounting the Propeller Blades along with Alternator or Generator and Tail.
Principle
The Windmill extracts energy from moving air by slowing down the wind, and transferring this harvested energy into a spinning shaft, which usually turns an alternator or generator to produce electricity. The power available in the wind that can be harvested depends on two factors i.e. wind speed and the area swept by the propeller blades.
