motor works on full-load with an efficiency of 94 per cent and a p.f. of 0.8 leading. [1510 V] (Electrical Machinery, Mysore Univ. 1992) 11. The synchronous reactance per phase of a 3-phase star-connected 6600 V synchronous motor is 20 2. For a certain load, the input is 915 kW at normal voltage and the induced line e.m.f. is 8,942 V. Evaluate the line current and the p.f. Neglect resistance. [97 A; 0.8258 (lead)] 12. A synchronous motor has an equivalent armature reactance of 3 3Q The exciting current is adiusted
