(OP)
if I have a 2 Y connection AC Motor, 115/200 Volt, 3 Phase, 400 Hz, ABC sequence...can I have 4 lead wires? or 8 lead wires?

Having been in the motor manufacturing business for over 15 years, I don't believe I've ever seen a neutral connection brought out of the windings. Of course I haven't seen everything either.

The is a company www.hobartgpu.com that has a 350 KVA 400 Hertz power supply that puts out 575 volts 3-wire 3-phase and up to 8 of these can be paralled. I did not find anything on how to buy stepdown transformers to get 155Y200 volts. I know that the Airbus 380 uses expletiveloads of power so perhaps that mostrosity uses 575 volts 400 Hertz - do not hold me to that.
They also have smaller inverters up to 180 KVA that turn 60 Hertz juice into 115Y200 volts 400 Hz. The units have a 12 pulse rectifier for the 60 Hertz input. There is a table there for the ground power requirements for a quite a few commercial aricraft.
They also carry a line drop compensator for the load end of the line that automatically does power factor correction because inductive loads have more voltage drop than resistaive loads at this voltage.
