If you need good 3 phase 400 Hz you can get a VFD which goes up that high and
program it to just sit there making 400 Hz.

Of course, for the more mechanically inclined.. what about a big flywheel
driving an alternator. You might be able to rejigger a car alternator. I
don't recall how many poles they have..
A motor driving a flywheel driving an alternator/generator is called a motor
generator set. Some implementations are called a diesel electric locomotive. We
used to use them as power conditioners for Cray class supercomputers. Also used
by many home machinists to generate 3 phase from single phase power.
Car alternators are generally 3 phase internally. Don't know if you could get
28vac out tho.
