Answer / bhusha

dc motor never drop the power factor of the motor because
in case of dc any circuit behaves as a resistive circuit.

if number of induction motors are connected then power
factor is drop, therefor it is necessary to connect power
factor correcting capacitor banks across motors.

Answer / rohit pareek

no, the dc motor doesnt drop thr power factor because no
induction effect is there in dc motor i.e. does not
generate reactive power
