A 480-V, 60 Hz, 400-hp 0.8-PF-leading eight-pole Δ-connected synchronous motor has a synchronous reactance of 1.0Ω and negligible armature resistance. Ignore its friction, windage, and core losses for the purposes of this problem.
(a) If this motor is initially supplying 400 hp at 0.8 PF lagging, what are the magnitudes and angles of E A and I A ?
(b) How much torque is this motor producing? What is the torque angle δ? How near is this value to the maximum possible induced torque of the motor for this field current setting?
(c) If |EA| is increased by 15 percent, what is the new magnitude of the armature current? What is the motor's new power factor?
(d) Calculate and plot the motor's V-curve for this load condition.

The following functions describe the oscillations in electric circuits and the vibrations of machines and structures. Plot these functions on the same plot. Because they are similar decide how best to plot and label them to avoid confusion.
Draw the developed diagram and show the positions of brushes.
It is required that the network be stable and that no component of its response decay more rapidly than K1e^-3t. Show that these conditions are satisfied if K2>0, |K1| 3K1. Crosshatch the area of permitted values of K1 and K2 in the K1-K2 plane.
