The 1200 KVA, 2,100 V synchronous motor is assumed to be a salient-pole machine with reactance Xdqrn= 1.9 ohm/phase and X= 1.6 ohm/phase. Neglecting all losses, find the maximum mechanical 3-phase power which this motor can deliver if it is supplied with electric power from an infinite bus at rated voltage and frequency and if its field excitation is held constant at that value which would result in unity-power factor operation at rated load.
