greeting.. it about my stator windings..

[h8]

why is the stator winding of alternator in a voltage regulation of amplifier circuit are generally star connected?

and also, why is the induced emf in a distributed ac winding is lower then in a concentrated ac winding?

i cant find thsolution of these questions in any book in our library... i appreciate it if someone could help me on these...

thanks alot..
from ME!!!

Perhaps you should do a search on the internet. I know the answers are out there.

i know!! that is why i am starting over here!!

are they any more valid reasons?? please be free to donate your knowledge... they are all welcome..

also to add, why the voltage regulation for unity and lagging power factor are positive, while that for leading power factor is negative?

thank you very, very much...
from ME!!

1. ///Please, would you rephrase or explain the context of:\\why is the stator winding of alternator in a voltage regulation of amplifier circuit are generally star connected?
2. why is the induced emf in a distributed ac winding is lower then in a concentrated ac winding?
///Distributed ac winding has losses along its length considered. Therefore, the induced emf is lower.
The concentrated winding is more on the lump sum parameter side. Visit
