Answer / guest

the inductance does not come into play in case of dc motors
as the reactance will become zero since the frequency of dc
is considered zero. hence we neglect the inductive drop.

Answer / jay

inductive drop is neglected because we study the steady state behavior rather than transient. since an inductor becomes shorted in steady state condition.
