I got the next info in YouTube...  it confirms previous information.

"I found a way around the lower RPM! if you simply rewind the alternator 
to have twice as many turns of insulated wire, it will be able to 
produce double the current at a given speed. The overall amount of power 
possible will drop, but this is probably not a problem, since most 
unmodified alternators will only give their maximum current at around 
6000 RPM."
