A 3-phase, 12-pole, star-connected alternator has 180 slots with 10 conductors per slot and the conductors of each phase are connected in series. The coil-span is 144° (electrical). Determine the phase and line values of emf if the machine runs at 600 rpm and the flux per pole is 0.06 weber distributed sinusoidally over the pole.
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.
