Extracted text: P6) A 3 phase, 2300V, 60HZ12-pole, Y-connected synchronous motor has X, = 4.5 ohm and negligible stator resistance. The machine is connected to an infinite bus. And draws 250 A at a 0.8 pf lagging. a) Determine the output power (neglect rotational losses) b) Determine the power to which the motor can be loaded slowly without losing synchronism. Determine the torque, stator current, and supply power factor for this condition.
