By Windmills Tech Editor. The blades, the hub, and the main shaft of a wind turbine harness the kinetic energy of the wind and convert it into rotational mechanical energy. The speed of this rotation is too slow to drive the generator efficiently, so a gearbox converts the high-torque and low-speed mechanical energy of the main shaft into the ...

Bergey Windpower Company (BWC) is a family-owned manufacturing and project development company formed in 1977 in Norman, Oklahoma. Their company produces three small wind turbines rated at 0.85, 1.5, and 10 kW (BWC 850, BWC 1500 and BWC EXCEL) and has sold 1,600 turbines worldwide since production began in 1980.
For this reason, gas turbines are treated in the article internal-combustion engine. The energy available in wind can be extracted by a wind turbine to produce electric power or to pump water from wells. Wind turbines are the successors of windmills, which were important sources of power from the late Middle Ages through the 19th century.

Wind turbine maintenance is a critical part of keeping turbines running smoothly and preventing downtime. There are a number of different things that need to be done on a regular basis to keep turbines in top condition. This includes inspecting the blades for damage, checking the gearbox for wear and tear, and cleaning the nacelle.
Gears & Gearboxes 101. A gearbox is typically used in a wind turbine to increase rotational speed from a low-speed rotor to a higher speed electrical generator. A common ratio is about 90:1, with a rate 16.7 rpm input from the rotor to 1,500 rpm output for the generator. Some multimegawatt wind turbines have dispensed with a gearbox.
