Huzzah! :-) - I got the diesel electric right :-).

He walks in both worlds.
Hacks new machines out of sheet steel and copper wire and strontium
ferrite unmagnetised blanks etc BUT at one time sold zillions of BLDC
motors to whirlpool. etc.

He also presumably has contacts back into his prior world.
And also we both have possible contacts of use in Taiwan for
manufacturing if desired.

I'll try and tidy that spec up and pass it on to him.
Better, any chance of you putting all that together in a paragraph or
so and posting it or sending it to me. I think it sounds of interest
to others and you may get some good alternatives.

Targets:
Alternator or Generator.
200+ Amp.
120 + V.
ACV or DCV out.
Internal means to suit designer.
Mass - as low as sensibly possible.
Anywhere in 1000-3500 RPM
low < $ %000

Questions:

Max hoped for mass?
Max hoped for size?
Fn(Mass, Size, $) =
Can RPM in be constant? (eg engine optimum).
