vindrotorer
Vindrotorer are the rotating components of a wind turbine that convert the kinetic energy of wind into mechanical energy. They are mounted on the nacelle atop a tower and consist of blades attached to a central hub. The rotor drives a shaft connected to a generator, either directly or through a gearbox.
Most modern rotors use three blades with aerofoil profiles designed for lift. Blades are made from composite
Rotor diameter determines the swept area and energy capture. Onshore rotors typically range from about 80 to
Performance and safety: rotors are designed to withstand fatigue, icing, and lightning. Maintenance includes blade inspection,
History and trends: wind rotors evolved from early experiments in the 20th century to the dominant three-blade
