           Self excited dc generators
           Windings – Armature and field

           Field windings --Series and Shunt
           Series field winding arein series with armature and have large cross section and few turns.
           Resistance of series field winding is small.
           Shunt field winding in parallel with armature having small cross section and large number of turns, resistance is
           more.
           Se lf excited dc series generator
           Series field winding are in series with armature and have large cross section and few turns.

           Resistance of series field winding is small. It has 4 terminals, 2of armature and 2of series field.






















           DC shunt generator
           Shunt field winding in parallel with armature. Shunt field windings small crosssection,largeturns,moreresistance.
           It has4 terminals, 2of armature and 2of shunt field.


















           DC compound generator
