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. Dwight

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
