How many wind zones does the generator rotor have

The gearbox reduces generator cost and weight. Commercial generators have a rotor carrying a winding so that a rotating magnetic field is produced inside a set of windings called the stator. While the rotating winding consumes a fraction of a percent of the generator output, adjustment of the field current allows good control over the output .

The largest turbine is GE's Haliade-X offshore wind turbine, with blades 351 feet long (107 meters) – about the same length as a football field.

How does a wind turbine generator work?

In a wind turbine generator, propeller-like blades spin around a rotor, spinning a generator, which creates electricity. As the wind blows across the rotor blades, a pressure gradient is formed between the upwind and downwind sides of the blade causing a resulting lifting force which pushes the blades clockwise around the main shaft.

What is the difference between upwind and downwind turbines?

Upwind turbines—like the one shown here—face into the wind while downwind turbines face away. Most utility-scale land-based wind turbines are upwind turbines. The wind vane measures wind direction and communicates with the yaw drive to orient the turbine properly with respect to the wind.
