The armature resistance of a 50 KW, 240 V foreign excited generator is 0.02 ohms. Generator Rated voltage is met at rated load. Armature voltage and armature current at rated load calculation? If the output voltage is kept constant at 240V and the output power is reduced to 45 KW. Find the armature voltage required for this?
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.
