8-pole 3-phase star-connected alternator with 144 grooves in its armature rotates at 900 rpm. There are 12 conductors in each groove in the armature of the alternator. The magnetic flux of one pole is 1.8.10 ^ 6 maxwels. Coils (1-16) were wound in -15 steps. Accordingly, find the phase and interphase voltages induced in the inductor of the alternator. (The speed of the alternator will be taken as synchronous speed ns.)
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.
