2 3. AD.C. series motor is connected to a 80 V dc supply taking 5 A when running at 800 rpm. The armature resistance and the field resistance are 0.4 01 and 0.6 01 respectively. Assuming the magnetic flux per pole to be proportional to the field current. (a) Determine the back e.m.f. of the motor. (b) Determine the torque of the motor. (c) The torque is found reduced by 20%. Determine the new armature of the motor.< (4 marks)< (4 marks)< (8 marks)<
