I recall we had a motor generator and fluid cooling for the 3033 we had. We also had 2
smaller ones as well ( forget the numbers ). They all ran 360 code..
It is astounding how far things have come from that time.

If I am right was this to create a stable power source at a certain
frequency or voltage?
I dont know about the 360, but a motor/gen can provide several benefits:
- isolate the load side from mains noise
- provide a degree of regulation from mains fluctuation thanks to the inertia of
the rotating mass
- raise the frequency so subsequent power supply transformers and caps can be
smaller (ala 400Hz operation in aircraft)
- convert to 3-phase as Chuck mentioned, although I would have thought that by the
time a 360 is running from a motor-gen
it's probably already being supplied with incoming 3-phase mains
