The armature of a 2-pole 200 V generator has 400 conductors and runs at 300 RPM. Calculate the useful flux per pole. If the number of turns in each field col is 1200, what is the average value of the electromotive force induced in each coil on breaking the field if the flux dies away completely in 0.1l sec?

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.
