In symmetrical 3-phase machines, the direct and quadrature axis stator currents isα and isβ are fictitious

quadrature-phase (2-phase) current components, which are related to the actual 3-phase stator currents as​

follows:​

isα = k (isa -1/2isb -1/2isc) EQ. 3-4

isβ =k(sqrt(3)/2)(isb -isc) EQ. 3-5​

Where:​

k = 2/3 is a transformation constant​

to get the answer you need to multiply by 3/2 to cancel out the transformation constant​

 

it is what happens when you try to revive a 2+ year old thread.

 

You CAN post to it. You have to select the box that says the following:

This was pointed out to me when I tried to post to an old thread. I received the message that said the thread is too old. You have to select this box first, then hit reply.

FYI That doesn't work for everybody for some reason. I've tried to post updates to my old works-in-progress before and it didn't work (despite checking the box). It's irritating though, as some people can. They dredge up years old posts by posting their own related (or not) question in there, and I can't post on my own old posts.

 

thank you for your time and have a good day
