Bad URL. I didn't notice that after a search the URL didn't contain the search info like Google does. Go to http://www.grainger.com and do a search on "belt-drive generator". That will bring up 6 different units, from 3 kW to 30 kW. (And yes, they play the "specmanship game": they're actually 2.4 to 25 kW.) The 4 kW unit I have is similar to these. I don't recall the voltage regulation specs, nor the exact mechanism, but you could boost the output voltage by putting AC capacitors on the output. The leading current component would increase the magnetization in the generator and raise the output voltage. Of course this had limits -- you could blow the generator by going too far. I did use a scope and a current probe to measure the phase angle of our well pump (a very noticably inductive load) and added capacitors to bring the reactance back to neutral. Things ran much better that way.
