Wind turbine components

Rotor blades: captures wind energy and convert it in to rotational energy of shaft.

Shaft: transfer rotational energy in to generator.

Nacelle: that holds gear box, generator, electronic control unit, yaw controller, brakes.
-> Gear box: increases speed of shaft between rotor hub and generator.
-> Generator: Use rotational energy of shaft to convert to electricity using electromagnetism/
-> Yaw controller: moves rotor to align with direction of wind.
-> Brakes: stop rotation of shaft in case of power overload or system failure.

Tower: supports rotor and nacelle and lifts entire set up to higher elevation where blades can safely clear the ground.

Electrical equipment: Carries electricity from generator down through tower and controls many safely elements of turbine.
