Thanks for all the time spend in this thread.
I learned a lot and will learn more reading it over a few times more.
Thanks all.

The motor has inductance so this changing stator current must produce an inductive voltage drop.
Hi jim,jim hardy said:thank you indeed, miles.
i'm a picture thinker not a math thinker.
Is this similar to "Armature Reaction" i learned fifty years ago? Which relates to Synchronous impedance ?
if so, it'll help me get fluent with this new(to me) FOC technique. I see it's been around since eighties at least...
curmudgeon that i am, i must admit that controlling a motor in this fashion is one of the most interesting things for a computer to do that I've ever seen .
just think what one could do with an H-bridge and an old car alternator...
thanks again

If, on the other hand, the magnetic axis of the stator is at a right angle to the magnetic axis of the rotor, maximum torque is produced. The objective is then to always keep I_sum at a right angle to the magnetic axis of the rotor (for a non-salient rotor).
