A four-pole, three-phase, Y-connected, non-salient pole synchronous motor has a synchronous reactance of 10 Ω. This motor is connected to a 230 V (line to line), 60-Hz, three-phase line and is driving a load such that Tshaft = 30 N-m. The line current is 15 A, leading the phase voltage. Assuming that all losses can be neglected, determine the power angle δ and E for this condition. If the load is removed, what is the line current, and is it leading or lagging the voltage?
