The blades of a 6 megawatt wind turbine weigh 70 tonnes, the rotor of the generator weighs 100 tonnes and the stator of the generator weighs 140 tonnes. The weight of the cabin is unknown, as is that of the tower.
First of all, it depends on the power of the large generator. We are debugging 3M wind turbines and preparing to develop 5Mw wind turbines. The heaviest part of the wind turbine is almost the tower and the nacelle above it. .
In addition, there are many types of towers, including cylindrical, lattice, and cement. The weights are also different, and it also depends on the manufacturer of the wind turbine, such as Vis in Denmark. Tasi One is built in a slimmer style and the engine room is also of the wind turbine type.

Development Prospects
Usually, people think that the power of energyWind power is entirely determined by the power of the wind turbine, and they always want to buy a bigger wind turbine, and that's incorrect.
The wind turbine only charges the battery, and the battery stores electrical energy. The amount of electrical energy people ultimately use is most closely related to the size of the battery. The power size mainly depends on the size of the air volume, not just the power size of the machine head. On the continent, small wind turbines are more suitable than larger ones.
How many times does a large wind turbine have?
Just find out the power of the wind. To find the power of the wind, its mass (the mass of the wind flowing at that second) and its speed (known) are essential, and I think you know how to find it. Perhaps you are a little vague on the concept of wind. In fact, you can abstract it as an object having amass to do work for the generator, and the conversion rate is 4%.
A large wind turbine weighs between 400 and 500 tonnes.
The blades of a 6 megawatt wind turbine weigh about 70 tons, the generator rotor weighs about 100 tons, and the generator stator weighs about 140 tons. Including the weight of the cabin and tower, it is approximately 460 tonnes.
Due to the unstable air volume, the wind turbine produces 13-25V alternating current, which needs to be rectified by the charger, and then the battery is charged, so that the electrical energy generated by the wind turbine is converted into chemical energy.
Generator Structure:
Nacelle: The nacelle contains the key equipment of the wind turbine, including gearboxes and generators. Maintenance personnel can enter the nacelle through the wind turbine tower. The left end of the nacelle is the rotor of the wind turbine, that is to say the pathem and the rotor shaft.
Rotor blades: capture the wind and transmit the wind force to the rotor shaft. On a modern 600-kilowatt wind turbine, each rotor blade is about 20 meters long and designed to resemble an airplane wing.
Axis: The rotor axis is attached to the low speed shaft of the wind turbine.
Low speed shaft: The low speed shaft of the wind turbine connects the rotor axis and the gearbox. On a modern 600 kW wind turbine, the rotor turns quite slowly, around 19 to 30 rpm. There are conduits in the shaft for the hydraulic system to activate the operation of the aerodynamic brake.
