What RPM do flight control motors spin at?

I'm writing a book of fiction and I'm trying to figure out how to use parts off of a 777 to create alternate power sources.

One idea is to create a wind-powered generator. That requires preferably a DC motor that normally spins at less than 1,000 RPM. I know the 777 has many surfaces controlled by flight control motors - and I'm pretty sure they're powered by 28V DC. My questions would be:

1) Roughly how many of these flight control motors are there?
2) Do they typically run at low RPM? (less than 1,000)

I considered using the 28V DC alternators that are on the plane, but it seems they have very high RPMs - which means they wouldn't work well mated to a low RPM wind system.

Any help is appreciated!
thanks,
ken
