Hello all,
Here's a note on my quest for 400hz supply :
After a long search for economical solutions for this, I discovered the ACS 335 series of motor drives made by ABB -- the solution turned out to be far simpler than i thought -
Myth 1: 400hz power supply converters are crazy expensive
Myth 2: You need 3 phase power supply in your pit to drive the converter
Myth 3: you need to source these units from the aviation world - and therefore $$
ABB makes several drives that suit builders looking to motorize seats, etc
The ACS 355 series offers many flavors:

You can select the current rating according to your needs - after hooking up my 355, i saw that each seat fwd/aft motor drew just .2 amps - moving both seats together drew .4A - For most uses a 5 A unit would do fine
The unit runs on a single phase domestic line, a 15A outlet is good enough - the output is a 3 phase completely programmable supply (Voltage/freq) -
This also opens up the doors to run many acft items that also run on 3 phase 115v 400hz like in-line blowers, etc - for OEM items that need a single phase 115v/400hz supply, you can use just a single line from the unit
The unit I bought has a capacity of 9Amps, far more i realized than i needed -
The Seat motors need 220V phase to phase - but pl check the specs on the units you have - also you'll need to get the pinout of the seat connector - it's usually a 5 pin connector, with 1,2,3 as phase and 4/5 as neut/gnd -
The version of the 355 i bought here locally from the dealer cost me appx 400.00 USD - note that this is an imported item here, so the cost would be less in Europe or the US
The units with a lower rating would be less than that - I was quoted 250USD for a 5A one
cheers!

!! Please check your country voltages for correct unit, or else ka-boom!!
