A 4 pole, 50 Hz star connected alternator has 15 slots per pole and eachslot has 10 conductors. All the conductors of each phase are connected in series and the winding factor being 0.95. When running on no load for a certain flux per pole, the terminal e.m.f. was 1825 volt. If the windings are lap connected as in a D.C. machine, what would be the emf between the brushes for the same speed and the same flux/pole. Assume sinusoidal distribution
Synchronous Generator
In comparison to an asynchronous generator, it is a machine where the rotor speed is equal to the rotating magnetic field produced by the stator, i.e., mechanical speed is equal to the electrical speed, thus called synchronous, and not asynchronous.
Salient Pole Rotor
Salient pole rotor includes a large number of exposed poles mounted on a magnetic wheel. The construction of a bright pole is as shown in the image on the left. The proposed poles are made of metal laminations. The rotor winding is provided on these poles and is supported by pole shoes.
