A Three-phase, 12 pole, Y-connected alternator has 108 slots and 14 conductors per slot. The windings
are (5/6 th) pitched. The flux per pole is 57 mWb distributed sinusoidally over the pole. If the machine runs
at 500 r.p.m., determine the following: (a) The frequency of the generated e.m.f., (b) The distribution factor,
(c) The pitch factor, and (d) The phase and line values of the generated e.m.f.?
