Used to be, we'd use a cobbled up dynamotor. Perhaps you could use your
connections to find a surplus ground support power supply. (Most of us know
that 400 Hz is used in airborne systems.)

I need to convert 115 vac 60 hz to 115 vac 400 hz 1 and 3 phase, 12 - 15
amps and 26 vac 400 hz single phase at a couple of amps. I want to
simplify the mess I spread around on my bench when I need 400 hz. I'd like
a single unit that gives me what I want. Is there a fairly simple way to
do this?
