Whether the Dc motor Droping the power factor like AC motor
if lot of motor running in factory is it necessary to
connect capacitor bank

Answer Posted / 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.
