The stator of a 3-phase, 16-pole alternator has 144 slots and there are 4 conductors per slot connected in 2 layers and the conductors of each phase are connected in series. If the speed of the alternator is 397 rpm, calculate (a) kc, (b) kd, and (c) the emf inducted per phase. The resultant flux in the air-gap is 5 x 10-2 webers per pole sinusoidally distributed. Assume the coil span as 150° electrica
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.
