7 Components of a Wind Generator

Pitch – refers to the angle of the blade

  • The pitch can be changed to increase or decrease the rotational velocity

Brake – is used to stop rotation

  • On the Acciona AW-1500 turbine, the brake is a single disk.

Low Shaft Speed

  • On the Acciona AW-82/1500 turbine, the low-speed shaft rotates at a max of 16.7 rpm.

High Shaft Speed

  • On the Acciona AW-82/1500 turbine, the high-speed shaft rotates at 1320 rpm.

Gearbox

  • On the Acciona AW-82/1500 turbine, the gearbox ratio is 1:78.  For every 1 revolution of a blade, the generator spins 78 times.

Nacelle

  • The nacelle is the covering that encloses the generator, gears, brakes, etc.

Yaw Drive + Motor

  • The towers are 80 meters high in a standard Liberty 2.5MW turbine system.
