Vergel,

You might check out the Open Source Motor Controller group at
osmc@yahoogroups.com, but even then you'd be a bit off-topic
since it's primarily a DC controller (I think) but check into
their archives as AC motors have been discussed in the past.

I'm sure there are other groups that may cover your interests
as well so search for those groups, but this isn't really the
place as far as I'm concerned. Someone else with your same
interests isn't likely to say to themselves "the ExpressPCB
yahoo group is a good place to look for 5phase motor controller
circuit".

rgds,
