Bruce,

Not exactly right unless you are talking about the variable speed generators such as the Onan Quiet Diesel, which is actually a generator/inverter package.

On all "regular" generators the frequency (Hz) is absolutely dependent on the speed.  A four pole generator must run at exactly 1800 RPM to get 60 Hz.  The voltage is dependent on the design and field current which is controlled by the voltage regulator. 

       Thanks, Len.  There sure if a big array of "technology" out there, isn't there?

Well, just about everything I own is low tech, including me!!

However, most generators are pretty much the same physically, it is only in the controls/electronics that they are different. Pretty much like clothes washers and dryers, all old stuff inside but new flashy electronic panels on the outside!

I'm no electrical engineer, my posts are based on what I've done with my two gensets in the past three months. It has been a quick education.
