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
• Armature winding
• Series field winding and
• Shunt field winding
• 6 terminals,
• 2of armature, 2of series field and 2of shunt field
