PMSM - Lm = 1.5Ls ?
I'm refering to 3ph (non-salient) permanent magnet synchronous machines. I read an article quoting that:
Lm = 1.5 L ---- (1)
where Lm is magnetising inductance and L is self inductance.
Do you have any idea how to derive eq(1)?
By the way, in the article it states that the synchronous inductance Ls:
Ls = Lm + Lls ---- (2)
where Lls is leakage inductance.
Can I say that self-inductance (L) is in fact the synchronous inductance (Ls) of the machine?
Thanks.
