8. A 2-pole d.c shunt motor operating from a 200 V supply takes a full-load current of 35 A, the no- load current being 2 A. The field resistance is 500 2 and the armature has a resistance of 0.6 0. Calculate the efficiency of the motor on full-load. Take the brush drop as being equal to 1.5 V per brush arm. Neglect temperature rise. Rajiv Gandhi Tech. Univ Bhopal. 20001 (82.63%)
