WebDC Generator is classified according to the methods of their field excitation. By excitation, the DC Generators are classified as Separately excited DC Generators and Self-excited DC … WebThe armature circuit for a DC machine and two circuit connections for the armature and field circuits, a shunt connected machine and a separately excited machine are presented. The … For a machine using field coils, as is the case in most large generators, the field must be established by a current in order for the generator to produce electricity. Although some of the generator's own output can be used to maintain the field once it starts up, an external source of current is needed for starting the generator. In any case, it is important to be able to control the fiel… northern word for stream
