These are the generators whose field magnets are energized by some external dc source such as a battery. The diagram of the main parts of a 4 pole dc generator or dc machine is shown below.

In self excited dc generator the field coils mat be connected in parallel with the armature in the series or it may be connected partly in series and partly in parallel with the armature windings. The field winding has high resistance and more number of turns so that only a part of armature current passes through field winding and the rest passes through load. Converts the induced alternating current in the armature conductor into the unidirectional current in the external load circuit in dc generator action whereas it converts the alternating torque into.
