A 4-pole, 60 Hz synchronous machine has an axial length of 120 mm, an air gap diameter of 80 mm and concentrated coils with 150 turns. The angle described by the sides of the coils is equal to 165 electrical degrees. The flux density distribution is cosine with an amplitude of 0.6 T. Calculate the effective value of the electromotive force induced in the coils.
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.
