synchronous generator runs at 250 rpm and generates at 50-Hz. There are 216 slots, each containing 5 conductors arranged in a full-pitched winding for 3-phase star connection. All the conductors of each phase are in series and the flux per pole at no-load sinusoidally distributed over the pole pitch is
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.
A synchronous generator runs at 250 rpm and generates at 50-Hz. There are 216
slots, each containing 5 conductors arranged in a full-pitched winding for 3-phase
star connection. All the conductors of each phase are in series and the flux per
pole at no-load sinusoidally distributed over the pole pitch is 30 mWb. Find the emf
induced in each phase winding and the terminal voltage.
