SOLVED: The resistance of the armature of a 250V shunt motor is 0.3 ohm and its full load speed is 1000 rpm. Calculate the resistance to be inserted with the armature to reduce the speed with full load torque to 800 rpm. The full load armature current is 54A. If the load torque is then halved, at what speed will the motor run?
