The flux density distribution in the air-gap of a certain generator is such that it contains a fundamental, a third harmonic, and a fifth harmonic. The flux per pole due to the fundamental distribution is 9 x 10-3 weber, that due to the third harmonic distribution is 0.9 x 10-3 weber, that due to the fifth harmonic distribution is 0.4 x 10-3 weber. There are four armature slots per phase per pole, the connection are made for three-phase wye, and the coil pitch is 12/15. The frequency is 60 cycles and the generator has 4 poles. (a) Calculate the emf/turn. (b) If there are six turns/coil and two coil sides/slot, calculate the emf per phase. (c) Calculate the emf between line terminals.
