In practical there is no dc generator.Induced emf in an
any generator is always ac,but by using commutator we are
converting ac in to unidirectional supply.So the dynamo is
an electrical equipment which consists of commutator and it
gives unidirectional curent[not perfect DC]. The another
name of the dynamo is called as DC GENERATOR.
Alternator is an electrical equipment which dont have
commutator arrangement and it gives ac supply.

the names independent of the size .
