iii) A shunt motor runs at 70 rad/sec from a 460V supply and takes in an armature current of 100A. Resistors of 2.52 ohms and 1.64 ohms are connected in series with the armature and in parallel with the armature respectively. The field excitation remains direct from the 460V supply but the generated torque is halved. Determine the new running speed. Neglect brush voltage drop. The armature resistance is 0.4 ohms. [15]
