Cabin: cabin inclusive wind generator with the key equipment, including gear boxes, generators. Maintenance personnel can enter the cabin through the wind turbine tower. Left is the wind turbine rotor cabin, that the rotor blades and shaft.

Rotor blades: captured by the wind, and wind sent to the rotor axis. Modern 600 kW wind turbines, each rotor blade measuring approximately 20 meters and is very like the aircraft wing design.

Axis: Axis low-speed small wind turbine attached to the shaft.

Low-speed shaft: the low-speed home wind turbine rotor shaft axis and gearbox together. In the modern 600 kW wind turbine, the rotor speed very slow, about 19 to 30 rpm. Shaft in the hydraulic system for the catheter, to stimulate the operation of the air force gate.

Gearbox: gear box on the left is the low speed shaft, which can high-speed shaft rotational speed increased to 50 times the speed axis.

High-speed shaft and mechanical gates: high speed shaft to 1500 rpm operation, and drive the wind turbine generator. It is equipped with emergency mechanical brake, brake failure for the air force, or the wind generator is maintenance.

Generator: Usually referred to as asynchronous induction motor or generator. In modern wind turbines, the maximum power output is usually 500 to 1500 kilowatts.

Yaw device: With motor rotating cabin so that the rotor is facing the wind. Yaw device operation by the electronic controller, electronic controllers to feel the wind through the wind vane. The figure shows a wind turbine yaw. Typically, the wind changed its direction, the wind turbine will deflect a few degrees.

Electronic Controller: Includes a continuously monitor the state of wind turbine computer, and yaw control device. To prevent any failure (that is, gearbox or generator overheating), the controller can automatically stop the rotation of wind turbines, and through telephone modem to call wind turbine operators.

Hydraulic systems: wind turbines for the air force reset gate.

Cooling Components: contains a fan for cooling generators. In addition, it contains an oil cooling device for cooling gear box oil. Some home wind generators have water-cooled generator.

Tower: vertical wind turbine towers and rotor containing the cabin. The tower has the advantage of generally high because of the higher off the ground, the greater the wind speed. Modern 600 kW wind turbine tower height is 40 to 60 meters. It was tubular tower, it can be lattice-shaped tower. Tubular towers safer for maintenance personnel, because they can reach the top of the ladder inside. Grid tower is that it is cheaper.
