1. A twelve-pole, AC single phase alternator has 144 slots, 2/3 of which are wound with 8 conductors/slot. The flux per pole is 42 mWb, sinusoidally distributed. The distribution factor is 0.829 and the coil span factor is unity. If the speed is 500 rev/min, find emf generated.
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.
