The machine shown in Figure 2 has three concentrated stator coils, each of eight turns. The coils are arranged symmetrically around the stator at 120° intervals. The poles of the rotor are so shaped that the air-gap flux density due to the rotor mmf is nearly sinusoidally distributed. The total rotor flux is 0.040 Wb. The rotor is driven at 3000 r./min. (a) Determine the frequency of the voltages generated in the coils. (b) If the stator terminals a', b' and c' are connected to form a Neutral point o, find the rms voltage between any two of the terminals a, b,and c. Figure 2 be J.
