Electrical EngineeringQ&A LibraryA 500 V dc shunt motor has an armature resistance of Ra = 0.25 2 and field circuit resistanceof R 240 . The motor drives a mechanical load, which requires a torque proportionalto speed. When the motor-load system is connected to a 500 V supply, it takes 100 A and rotatesat 1100 rpm.The speed is to be reduced to 900 rpm by inserting a resistance in series with the armatureThe field current is kept the same.Determine the value of the added series resistance.Question
