Parts of Wind Turbine
Following are the
different parts of the wind turbine:
- Blades
- Rotor
- Nacelle
- Gearbox and coupling
(transmission system)
- Aero turbine
- Controller
- Electrical generator
- Supporting structure
The Rotor& Blade:
The blades are
lightweight, durable, and corrosion-resistant material. The best materials are
composites of fiberglass and reinforced plastic.
Nacelle
A housing that
contains all the components which are essential to operate the turbine
efficiently is called a nacelle. It is mounted on top of a tower and includes gearboxes, generators, low and high-speed shafts, controllers, and brakes.

Important Key Points
Ø The speed of the wind turns the blades of a rotor between
10 and 25 turns per minute.
Ø Each turbine is made up of a mast between 20 m and 100
m according to the power of the machines.
Ø Wind speeds of between 14 and 90 km/hour.
Ø The electricity produced is generally stepped up to the
voltage of the network 20 kV
Ø The blades face the wind; this can be done with a wind
direction sensor connected with a motorized head moving mechanism (or yaw).
