A couple of good machining turbine rotors photos I located:

Turbines and Towers
127 wind turbine generators, spanning across 9,000 acres near Ellensburg, Washington.
Towers are 221 ft higher at hub, 13.2 ft wide base and 7.6 ft wide at leading and weigh 104 tons. Every turbine consists of 3-blades, 129 ft lengthy, 11.62 ft at widest and 1.6 ft at tip with every single blade weighing 14,300 lbs. The rotor (blades, hub and nose cone) weighs 42 tons.
Turbine generators are V80-1.8 MW machines manufactured by Vestas, a Danish company. Every generator can make 690 volts, which is stepped-up to 34,500 volts by an on-board transformer. The generator is housed inside a fiberglass nacelle.
The generator and nacelle with each other weigh 69 tons.
Total height with a blade completely extended is 351 ft and total weight is around 270 tons. These are the largest wind turbine generators in Washington State (as of 2007)
Each and every tower foundation reaches a minimum depth of 25 ft and a maximum of 32 ft depending on bedrock depth and requires an typical of one hundred to 260 cubic yards of concrete. Each and every foundation calls for 120 anchor bolts that span from the surface of the ground to the bottom of the foundation. A single 28 ft anchor bolt weighs about 150 lbs.
Rotors turn 15.5 rpm, turning clockwise (front view) with a rotor diameter of 264 ft, bigger than a wingspan of a Boeing 747.
Turbines can make electrical energy at wind speeds as low as 9 mph, reaching their peak of production at 31 mph and shut down at continuous wind speeds of 56 mph. The prevailing winds are from the northwest.
Every single turbine is capable of producing 1.eight megawatts, or a total of 229 megawatts of capacity, sufficient electricity to serve roughly 73,000 residences when all 127 are generating at complete capacity.
