The one that runs a constant speed is much older (about the same age as mine) it runs I believe at 1800 RPM and by some magnetic magic that feeds out 60 HZ (3600 cycles) it runs at the constant speed because that is the speed it needs to run at to make 60 Hz.
There's no "magnetic magic" involved at all. 1200 RPM generators have 6 poles, 1800 RPM's have 4 poles, and 3600 RPM's have 2 poles. That's all there is too it...
I know this as it's the field I trained in but to the untrained "Magnetic Magic" is easier to type than the full explanation.
