The rotor is the part of the windmill that catches the wind and converts it into kinetic energy. It consists of blades that are attached to a central hub. The blades are usually made of fiberglass or a similar composite material, and they are designed to be aerodynamic so that they can catch the wind efficiently.
2. Windmill Body
The windmill body contains the main structure of the windmill, including the gearbox, generator, and other components. The body is usually made of steel or concrete, and it is designed to be strong enough to withstand high winds.
3. Gearbox
The gearbox is a crucial component of the windmill. It connects the low-speed rotation of the rotor to the high-speed rotation of the generator. The gearbox is also lubricated and cooled.
4. Generator
The generator is another essential component of the windmill. It converts the kinetic energy of the rotor into electrical energy. The generator is cooled by the air that flows through the turbine, and it is also equipped with a voltage regulator to ensure that the output voltage is maintained at a constant level.
5. Tail Assembly
The tail assembly is located at the back of the windmill, and it is responsible for keeping the windmill facing into the wind. The tail assembly consists of a rudder and a vane. The rudder is attached to the hub of the rotor, and it turns the windmill so that it faces into the wind. The vane is a small horizontal propeller that senses the direction of the wind, and it turns the gearbox so that it is in line with the vane.
