Concept explainers

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.

Question

A 6 pole, delta connected three-phase alternator having 144 slots is wound
using double layer lap coils having 7 turns per coil. The coil has
16 / 24 pitch.
The flux per pole is 7380000 maxuells. If the alternator
is driven at a speed of 700 rpm, determine the total line-to-line
generated voltage.
