A 6600 V three-phase star connected synchronous motor draws a full load current of 70 A at 0.8 power factor leading. Assume the stray losses total 30 kW and the armature resistance is 2.0 ohms and reactance is 20 ohms per phase. Find (i) the efficiency, (ii) the hp of the machine, and (iii) the e.m.f induced |
