Q#1(a): Illustrate the EMF equation of generator. Q#1(b): An 8-pole, lap-wound armature rotated at 350 r.p.m is required to generate 260V. The useful magnetic flux per pole is 0.07Wb. If the armature has 110 slots. Use appropriate equation to calculate the number of conductors per slot.
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.
