why inductancce of armature inductance of dc machines is
neglected?
Answer Posted / suantak
The inductive reactance offered by an inductor or coil is
null when a dc current pass through it. The reactance
offered by the armature of dc machine is zero, considering
an ideal dc current withough harmonics (in fact a small
amount of reactance will exist due to harmonics).
This is may be the reason why armature inductance is
neglected. Please note that this is my view and it is not
from any book, journal or publication.
