Types of dc generators are classified by the connection of the field winding and how it gets excited in the generator. Therefore, based on the field excitation, dc generator is classified as –

  1. Separately Excited DC Generator
  2. Self Excited DC Generator

Separately Excited DC Generator: As the name implies, a separate or different dc supply is fed to the field winding and the voltage is taken from the armature in this type of generator. 

The above picture shows the dc supply by which a current flows through the field winding known as field current. It will produce the required flux which is cut by armature. Thus emf is induced in the armature conductor. The armature is shown in the right side of the above figure which is directly connected with the load. The armature current (Ia) which is actually flows through the load. Hence, Ia = IL
