Calculate the voltage per phase for a 3-phase 1500 rpm, 4-pole alternator having a double layer winding with 16 turns per coil. The slots per pole per phase are 8 and the coil span is 20 slots. The phase spread is 60° and the flux per pole is 25.8x10−3 weber.
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.
