There are 180 double wound slots in a 3-phase, 50 Hz., 500 rpm, star connected alternator. Coil span is 15 slots and there are 3 turns per coil. Flux per pole is 0.1135 WB. Calculate (1) emf per conductor (2) emf per coil.
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.
