An example of a wind turbine, this 3 bladed turbine is the classic design of modern wind turbines Wind turbine components : 1-Foundation, 2-Connection to the electric grid, 3-Tower, 4-Access ladder, 5-Wind orientation control (Yaw control), 6-Nacelle, 7-Generator, 8-Anemometer, 9-Electric or Mechanical Brake, 10-Gearbox, 11-Rotor blade, 12-Blade pitch control, 13-Rotor hub
The generator, which is approximately 34% of the wind turbine cost, includes the electrical generator, [64] [65] the control electronics, and most likely a gearbox (e.g., planetary gear box), [66] adjustable-speed drive, or continuously variable transmission [67] component for converting the low-speed incoming rotation to high-speed rotation ...
If the turbine is allowed to speed up immediately when hit by a wind gust, the stresses are lower with the power from the wind gust still being converted to useful electricity. One approach to allowing wind turbine speed to vary is to accept whatever frequency the generator produces, convert it to DC, and then convert it to AC at the desired ...

The world's tallest vertical-axis wind turbine, in Cap-Chat, Quebec Vortexis schematic Vertical axis wind turbine offshore. A vertical-axis wind turbine (VAWT) is a type of wind turbine where the main rotor shaft is set transverse to the wind while the main components are located at the base of the turbine. This arrangement allows the generator ...
The wind pushes each blade around on both the windward and leeward sides of the turbine. The qr5 turbine, rated for 6.5 kW, measures 3.1 metres (10 feet) in diameter [5] and 5.5 metres (18 feet) high. [6] The qr6 is similar: 3.1 m wide and 6 metres (20 feet) tall and is rated 7.5 kW. [7]
