A 240 V dc shunt motor takes 10A and 30A at no load and full load respectively It is having armature resistance of 0 4 ohm and field resistance of 120 ohm Considering iron friction and windages losses are negligible Then examine the various parameters 1 armature current at no load and full load condition 2 Back emf at no load condition 3 Back emf at full load condition 4 Ratio of back emf from no load to full load condition
