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)

What will be the size of copper cable (each for 3 phase and 1 neutral) from Service connection Kit-Kat to Panel Board (i.e. to main switch) for a 6 pole 3-phase AC induction motor of 200 H.P. capacity? Amp-255 A, Frequency:- 1450 rpm.
