Answer / kiran

since f=0, xl=o and hence drop Ixl=0.so there is no inductive drop in dc motors.

Answer / abhishek srivastava

the reason behind this query.

dc motor operated by direct current supply and inductor
passes dc current its frequency is zero and drop is very
small so we neglected this in practical.formula of inductor
is (1/2LI*2)

Practical condition in 400KV Sub station:- Breaker(open) , isolator(open), Earthing (close) at both end e.g A & B. Now Open A Stn Earthing than Open B stn Earthing (Which have a 50MVA reactor) , AND suddenly show R,Y,B phase 704KV,573KV,118KV respectively. Que is without closing of breaker how it is possible.????
