DC Generator Construction Summary
+
A shunt-wound DC generator is constructed so that the field winding is in parallel
with the armature winding.
+
The voltage of a shunt-wound DC generator decreases with an increase in load
current.
+
A series-wound DC generator is constructed so that the field winding is in series
with the armature winding.
+
The voltage of a series-wound DC generator increases sharply with an increase in
load.
+
In a cumulatively-compounded DC generator, the series and shunt fields aid one
another.
+
In a differentially-compounded DC generator, the series and shunt fields oppose
one another.
+
The voltage of a flat-compounded DC generator changes less than 5 percent from
no-load to full-load.
+
The voltage of an over-compounded DC generator gradually rises with an
increasing load.
Summary
DC generator construction is summarized below.
