A 4 pole machine generates 250 volts when operated at 1500 rpm. If the flux per pole is 1.85 x 10°maxwell. The number of armature slots is 45 and the armature winding has two parallel paths. Calculate. a). the total number of armature conductor. b). the number of conductor in each slot c). If the speed of the generator is decrease to 1,350 rpm, what will be the generated voltage if the flux per pole is maintained at the value. d). To what value of flux per pole should the excitation be adjusted if the generated voltage is to remain the same. (Hint: Eav and Eg = lave ) ØXP t

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.
