Question: A 2 4 0 V , 1 0 0 0 hp DC shunt motor delivers power to a load at 1 8 0 0 r

A 240 V,1000hp DC shunt motor delivers power to a load at 1800r/min. The armature current drawn by the motor is 200 A. The armature circuit resistance of the motor is 0.2 and the field resistance is 100. If the rotational losses are 500 W, what is the value of the load torque? What will be the efficiency of the motor. What is the Speed regulation (SR) if the no-load is 1900r/min. What happens when a DC motor is connected across an AC supply?
