An alternating current generator has a square loop (with side length a) mounted on a vertical shaft as shown in the figure. This square is rotating at angular velocity w. A uniform magnetic field 3 points to the right. The figure at the bottom shows the view from the above and s is the surface vector of the loop. Determine the induced emf, &(t) for this generator.

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.
