Please go through the construction of dc generator before reading this article about different types of dc generator.. A DC generator requires MMF to establish flux in its magnetic circuit. The MMF necessary to establish flux in the magnetic circuit of a dc generator is obtained by field excitation.
Operation of DC generator PRINCIPLE: Whenever a conductor cuts magnetic flux, dynamically induced emf is produced in it. ( Faraday's Laws of Electromagnetic Induction ). This emf causes a current to flow if the conductor circuit is closed. OPERATION: Field winding produces magnetic field in D.C. generator. Armature is coupled to the prime mover. Prime mover produces torque so the armature rotates.
The dc generators and dc motors have the same general construction. In fact, when the machine is being assembled, the workmen usually do not know whether it is a dc generator or motor.
