@sledhill Are you putting this on all the wind turbine vids? I'm assuming you're a troll fishing for reactions from those "nutjobs" who love windmills; if so, you're doing a very poor job of trolling.
They don't "use electricity to start a generator". The unit simply steers into the wind using electric actuators that rotate the nacelle, also, they move the blades in such a way to get a constant rotor speed from different speed winds. The steering mechanism follows the wind via instrumentation atop the exterior of the nacelle and as you can see by the rotation of the inside of the hub, it quickly in less than a second offsets any power used by the steering and blade actuators.
@klingzz, number of poles on the rotor isn't a problem, just need enough of them to give 50Hz (or 60, if you prefer) and a big enough diameter so they pass the slots in the stator (which is where the power is generated) fairly quickly. Big plus for direct drive is no big, heavy, expensive, noisy gearbox. More power ? - make the poles and stator longer along the direction of the shaft
@brandonakers Is direct drive, just like a lot of home-made turbines up to about 3kW using rewound Fisher-Paykel washing machine motors (Variable-frequency synchronous with permanent magnet rotor)
thats a really nice view of the generator... take notice of the large number of poles they have to use in this kind of gearless generators... thats why they need to be so large in diameter... and that is why it is so difficult to build them any larger than 6MW...

what's that clicking sound? are these perm magnets or electromagnets?

what the heck?? This looks way different from what I work on everyday, this must be a direct drive?

the largest one ever build was about 6MW... normally they can produce about 3.6 MW as far as i remember...

The poles are the small boxes on the outer rim of the rotor ... just to make that clear!!

they use ELECTRICITY to start a GENERATOR??
THATS KIND OF SAD...

@cheetawolf not really. It's just like the starter for a car engine. And the engine is basically a power generator.

I was just thinking the SAME thing! How much electricity does this use to make some???
