A 4 pole wave connected, armature of the DC shunt wound generator is connected to the following loads connected in parallel. a) 4KW Geyser at 220V b) 4.5KW load at 220V The generator has an armature resistance of 0.2 ohm and a field resistance of 230 ohms. The armature has 150 conductors in the slots and run at a speed of 1400 rpm. Allow 1V brush contact drop and neglect friction and windage losses. Determine the flux per pole of the machine. Draw the illustration of electrical equivalent circuit with marking of computed value and given values)
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.
