Consider a shunt DC motor with an armature resistance RA =0.2N and terminal voltage VT = 160 V. The motor rated speed is 1800 RPM. The total field resistance 240 Q. Assume No armature reaction in this machine. The variation of the armature terminal voltage as a function of the field current is measured under no-load conditions and shown below: IF (A) EA (V) 1.0 141 0.0 0.6 125 These values were taken at speed n= 1800 RPM 0.1 0.2 0.3 0.4 0.5 0.7 0.8 0.9 30 60 85 102 115 132 137 140 If the motor is driving a load at an armature current IA=60 A, its rotational speed is 1517 RPM, with rotational losses of 848 Watt. What torque is induced by this motor? Select one: O a. Induced Torque = 62 N.m O b. Induced Torque = 56 N.m O c. None O d. Induced Torque = 51 N.m.
