Rotor Blades
Rotor blades are designed to capture the wind's kinetic energy and convert it into rotational energy.
Hub
The hub is the central component that holds the rotor blades and connects them to the main shaft.
Nacelle
The nacelle houses the generator, gearbox, drive train, and other mechanical components needed to produce electricity.
Gearbox
The gearbox increases the rotational speed from the rotor to the speed required by the generator to produce electricity.
Generator
The generator converts the turbine's mechanical energy into electrical energy through electromagnetic induction.
Yaw System
The yaw system allows the turbine to rotate about the vertical axis to align the rotor with the wind direction.
Tower
The tower supports the nacelle and rotor, elevating them to heights where wind speeds are higher and more consistent.
Anemometer
An anemometer measures the wind speed and transmits the data to the controller to optimize turbine performance.
Controller
The controller starts and stops the turbine to protect it from high winds and to control its operation for maximum efficiency.
Brake
The brake can slow or stop the rotor mechanically, electrically, or aerodynamically, for maintenance or emergency shutdowns.
Pitch System
The pitch system adjusts the angle of the rotor blades to control the turbine's rotational speed and power output.
Transformer
The transformer adjusts the voltage from the generator level to the level suitable for the power grid.
Foundation
The foundation supports the tower and ensures stability, transferring the loads to the ground.
Power Converter
The power converter manages the flow of electrical energy from the generator, ensuring the current matches the grid requirements.
Wind Vane
A wind vane measures the wind's direction and communicates with the yaw system to properly orient the turbine.
