That'd make one screaming (literally) jacobs ladder if you could find a ferrite core big enough.

Hi Ed,
Naw, I forget, just remember it was a huge GE motor. Tell you what though, the generator was rather wide, a bit more than the 60 Hz motor. On that output, I remember it was 600 volts , two wire, at 10,000 Hz. Also, it took what seemed like at least 2 or so minutes to get to speed (the whole system, the inrush was so great it had a step start) and once you shut the thing down it spun down for several minutes. All that mass spinning..

"Hi Ed,
              As I remember it, when we moved that 10,000 Hz MG
set,  480 volt, 3 phase 150 HP driven, we had to pack a few extra
people on the back of the forklift so it could steer. Later, when
riggers came with a flat bed to take it for the client, we heard it
was about 9,000 pounds.
It was skid mounted like a typical diesel generator, maybe 4 feet
deep, 8 feet long, averaged 4 1/2 feet high, not fully enclosed.

Not surprising.  Was most of the weight in the 60 Hz motor?  150 hp is
pretty big by my standards.  Was it induction or synchronous or do you
remember.
