generator Device for producing electrical energy. The most common is a machine that converts the mechanical energy of a turbine or internal combustion engine into electricity by employing electromagnetic induction. There are two types of generators: alternating current (an alternator, such as found in power stations) and direct current (a dynamo). Each has an armature (or ring) that rotates within a magnetic field creating an induced electric current.
