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
English: A turbine and gear box are mounted in a casing called a nacelle, and rotor blades are attached to the turbine. The turbine localizes the energy of the turning rotor blades in a single rotating shaft that generates electricity.
Schematic representation of a gear rim with teeth on the inner side. The gear rim meshes with four yaw drive pinions.. The gear-rim and the pinions of the yaw drives are the components that finally transmit the turning moment from the yaw drives to the tower in order to turn the nacelle of the wind turbine around the tower axis (z axis).
A nacelle / n ə ˈ s ɛ l / is a cover housing that houses all of the generating components in a wind turbine, including the generator, gearbox, drive train, and brake assembly. [1]
In the event of skew winds the "wind pressure" on the swept area causes a yawing moment around the tower axis (z-axis) which orients the rotor. [1] The tail fin (or wind vane) is commonly used for small wind turbines since it offers a low cost and reliable solution. It is however unable to cope with the high moments required to yaw the nacelle ...
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 ...

The yaw bearing is the most crucial and cost intensive component of a yaw system found on modern horizontal axis wind turbines. The yaw bearing must cope with enormous static and dynamic loads and moments during the wind turbine operation, and provide smooth rotation characteristics for the orientation of the nacelle under all weather conditions.
