Question asked by Shawn Mathew  

Q. A 3 phase, 50 Hz, 2 pole, star connected turbo alternator has 54 slots with 4 conductors per slot. The pitch of the coil is 2 slots less than the pole pitch. if the machine gives 3300V between lines on open circuit with sinusoidal flux distribution, determine the useful flux per pole.

Thanks Shawn Mathew for asking the doubt, Hope I have cleared the same.

Coming to our second doubt asked by Paulraj.

Q. A 4 pole, 50 Hz, star connected alternator has 15 slots per pole and each slot has 10 conductors. All the conductors of each phase are connected in series, the winding factor being 0.95. When running on no-load for a certain flux per pole, the terminal emf was 1825 volt. If the windings are lap-connected as in a dc machine, what would be the emf between the brushes for the same speed and the same flux/pole. Assume Sinusoidal distribution of flux.

Thanks Paulraj for asking the doubt.
