Question
A 1000-V, 3-phase, 2-pole, Y-connected synchronous motor runs at 750 r.p.m. The excitation is constant and corresponds to
an Open-circuit terminal voltage of 1000 V. The resistance is negligible as compared with synchronous reactance of 1.50 per
phase. Determine the power input, power factor and torque developed for an armature current of 100 A.
