Any machine that converts mechanical energy to electrical energy or electrical to mechanical energy is called a dynamo 

When a device converts from mechanical to electrical energy, it is called a generator 

When a machine converts electrical energy into mechanical energy it is called a motor

There are two classes of generators the alternating current;

(a.c) generator or alternator and the direct current (d.c) generator or dynamo
