The compound wound generator has both series field winding and shunt field winding. One winding is arranged in series with the armature, and the other is arranged parallel to the armature. These types of DC generators are further classified into two types. Short Shunt Compound Wound DC Generator; Long Shunt Compound Wound DC
Compound winding. In a shunt-wound generator, output voltage varies inversely with load current. In a series-wound generator, output voltage varies directly with load current. A combination of the two types can overcome the disadvantages of both. This combination of windings is called a compound-wound dc generator. See also. DC motor
The output of a compound wound generator is relatively constant, even with changes in the load. Figure 12. Compound wound generator: Generator Ratings A DC generator is typically rated for its voltage and power output. Each generator is designed to operate at a specified voltage, approximately 14 or 28 volts. It should be noted that aircraft
Compound wound generator. Compound wound DC generators are those that combine series and shunt fields. Furthermore, we often use a cumulative compounded DC generator, meaning the magnetic flux the series winding produces helps the one the shunt winding produces. Those are frequently seen in uses such as remote
