(c) A DC shunt motor with compensating windings as shown in Figure Q3(e) has a rating of 70 hp, 270 V and 1350 rpm with an armature resistance of 0.05 2. The field circuit, Red + Re has a total resistance of 3002 which produces a no- load speed of 1400 rpm while the shunt field winding has 1500 turns per pole. (1) Find the induced torque if the input current is 100 A and 200 A. PE (ii) Plot the torque-speed characteristic curve of the motor by using the result obtained in Q3(c)(i). Analyze your findings.
