A 2300-V, 3-phase, wye - connected, round rotor synchronous motor has a synchronous reactance of 3 ohms per phase and an armature resistance of0.25 ohm per phase. The motor operates on load such that the power angle is -15 degrees, and the excitation is so adjusted that the internally induced voltage is equal to the magnitude of the terminal voltage. Determine the armature current.
