PMSM (Five-Phase) Mutual Inductance Equations are Wrong!

Hi,

There is a big mistake in the inductance equation of the Five-Phase PMSM block (please see the link given below). There is no way to adjacent phase mutuals equal to non-adjacent (remote) mutuals as given below. Lab can not equal Lce or Lea can not equal Lbd.

Lab=Lba=Lce=Lec=−Ms+Lmcos(2(θe−2π/5))

Lea=Lae=Lbd=Ldb=−Ms+Lmcos(2(θe+2π/5))

Please prove me wrong. Now, I think maybe there are also mistakes in other equations too! Are there any correct equations or explanations?

This was indeed a discrepancy in the expressions for self-inductances. However, the other equations on the page are correct. This inconsistency in the expressions for self-inductances did not affect the functionality.
