The stator of a 3-phase, 16-pole alternator has 144 slots and there are 4 conductors per slot connected in two layers and the conductors of each phase are connected in series. If the speed of the alternator is 375 r.p.m., calculate the e.m.f. inducted per phase. Resultant flux in the air-gap is 5 x 10-2 webers per pole sinusoidally distributed. Assume the coil span falls short of full-pitch by an angle a equal to 30
