A 6-pole, 3-phase alternator has 72 slots and its wound double-layer with 5/6 pitch and each coil has 20 turns. If the flux per pole is 7.8x106 maxwells and the alternator is driven at 1200 rpm, calculate the total generated emf per phase and the line voltage.
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.
