Separately Excited Generators :
As a separate supply is required to excite field, the use is restricted to some special applications like electro-palting, electro-refining of materials etc.
Shunt Generators :
Commonly used in battery charging and ordinary lighting purposes.
Series Generators :
Commonly used as boosters on d.c. feeders, as a constant current generators for welding generator and arc lamps.
Cumulatively Compound Generators :
These are used for domestic lighting purposes and to transmit energy over long distance.
Differential Compound Generators :
The of this type of generators is very rare and it is used for special application like electric arc welding.
