Any machine that converts mechanical energyEnergy is the ability to do work. Energy exists in several forms such as heat, kinetic or mechanical energy, light, potential energy, and electrical energy. Units of Energy: The SI unit... More 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
