A 4 pole, three-phase, the star-connected alternator has an armature with 120 slots and 4 conductors per slot. It revolves at 1100 rpm. The flux per pole is 0.06 weber. Calculate Frequency of generation, Number of turns, and the emf generated if the winding factor is 0.92 and all the conductors in each phase are in series
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.
