An elementary four-pole, three-phase, 60 Hz alternator has a rotating flux of 0.0875 Wb. The number of turns in each phase coil
is 25. Its shaft speed is 1800 rev/min. Let its stator winding factor be 0.95 and find the following:
(a) The angular speed of the rotor
(b) The three phase voltages as a function of time
(c) The rms phase voltage of this generator if the stator windings are delta-connected
(d) The rms terminal voltage if the stator windings are wye-connected
