A 50 hp, 250 V, 1300 rpm dc shunt motor shown in figure below resistance of 0.05 Q. Its field circuit has a total resistance Ras + R of 20 Q, which produces a no-load speed of 1300 rpm when there is no amature reaction. However, the speed of motor becomes 1350 rpm at no load when there is an armature reaction. There are 950 turns per pole on the shunt field winding. At no load with armature reaction, the internal generated voltage is 220 V. (a) Find a speed of the motor when its input current is 125 A and there is an armature reaction of 1500 A.tums. (b) What is the induced torque? win
