What is it you actually want? Are you looking to buy this generator
and need a source? Do you want information about this generator?

Yes, I plan to buy the genset and am looking for the right source.

Minor ripple, flutter and noise is unavoidable in rotating
alternators, but a few parts per million may be possible and
practical. Your specs are not complete as you did not specify the
voltage at 400 hertz nor the frequency at 115 v ac It is chalanging to
derive 55 hertz or 60 hertz from the same shaft that produces the 400
hertz, (except by belt and pully) so this would be a separate motor
and alternator in most designs, unless 57 hertz is satisfactory which
is 1/6 th of 400.
 115 v ac at 400 hertz is easy as it involves a tap in the winding
assuming 205 volts or more is desired at 400 hertz. A transformer can
supply the 115 volts if not a tap. The 28 volts is also easy, even if
you need very low ripple. Likely high ripple is ok as it used to
charge batteries. Exactly what you want may be available surplus or
can be special built for you higher cost. A 60 KVA unit should be
completely satisfactory, except it will use slightly more fuel, but
that will be offset by less mainenance and longer life for the
equipment. Do you prefer diesel fuel, gasoline or methane?  Neil

That should have been 1/7 of 400 is a bit over 57 hertz.
6.5  times 60 is 390 which may be close enough to 400 if the 60 hertz
needs to be right on.  Neil

Our basic requirement is that in one phase we should get 115V AC 400Hz
max current 200 amps. And in the other phase 28.5V DC 40 amps max
current. In this phase the ripple-free factor can be +/- 2V
peak-to-peak.

What you have on the inside of the generator is of no interest to us
but for the above outputs. And we need only diesel fuel driven 50kVA
generator right on not 60kVA.

Please advise asap.

Hey guys !

It has been over two weeks since I last posted my clarification.
Please get back soonest/as soon as you read this message as I need the
genset urgently.

Thanks a ton,

gurjit1,

If you do not receive an answer to a question, often the reason is
that your fee is too low. Increasing the price will make it more
likely that a Researcher will devote some time to a search. At your
current price, the Researcher who successfully undertakes this project
will receive only $3.37 for his or her efforts. When we begin a
search, there is no certainty that we will find what we are seeking;
if the financial incentive is more attractive, Researchers will
probably be interested in giving this a try.

Ok ! How do I increase the fee ?
