Dynamo is basically a DC generator[1], i.e. an electrical machine which converts mechanical power into direct current electrical power. Dynamo is essentially just another name for an electric dc generator.
Generation of DC current in a dynamo is based on the Faraday’s law of electromagnetic induction. A dynamo consists of a field winding, armature winding and commutator-brush assembly. The field winding produces magnetic field. When the armature winding is rotated inside the magentic field, by an external force, an emf is induced in the armature winding. The commutator-brush assembly is for taking the induced current out of the machine (in case of generator action).
