5. A Y-connected, 50Hz, 12-pole, 3-phase synchronous generator has double-layer stator windings placed in the 180 stator slots, each containing 16 conductors. The coil pitch equals 12 slot pitch and the number of circuits is 1. Find the fundamental flux per pole that is needed to produce the line-line fundamental emf of 13.8 kV at no load.
6. A 3-phase induction machine has double-layer short-pitch stator windings. The number of stator slots is O=36, the number of pole pairs is p=3, the coil pitch is y=5 slot pitch, the number of turns per coil is N=20, the number of circuits is a=1, the frequency is f=50Hz, and the fundamental flux per pole is @=0.00398Wb. Find:
1. The fundamental rms emf of a conductor.
2. The fundamental rms emf of a single turn in a coil.
3. The fundamental rms emf of a coil.
4. The fundamental rms emf of a coil group.
5. The fundamental rms emf of a phase winding.
