A 10 kW, 250 V self-excited generator, when delivering rated load, has an armature circuit voltage drop that is 5% of the terminal voltage and a shunt field current equal to 5% of rated load current. Calculate the resistance of armature circuit and that of the field circuit.
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.
