Synchronous Motor (SM):
A 480-V, 100-kW, 60-Hz, six-pole, Y-connected synchronous motor has a
synchronous reactance of 1.5 2 and a negligible armature resistance. The
rotational losses are 5kW. Assume that the flux in the motor varies linearly with
the field current. For motor operating at 0.85 PF lag., the field current is 10.0 A.
Answer the following questions:
2) If the SM operates at 0.85 PF lagging and rated load, calculate the line
current and the input power. Calculate induced voltage of SM for this case.
