AC Generators AC GENERATOR COMPONENTSAC GENERATOR COMPONENTSAC generators are widely used to produce AC voltage. To understand how thesegenerators operate, the function of each component of the generator must first beunderstood.EO 1.1 STATE the purpose of the following components of anAC generator:a. Fieldb. Armaturec. Prime moverd. Rotore. Statorf. Slip ringsFieldThe field in an AC generator consists of coils of conductors within the generator that receive avoltage from a source (called excitation) and produce a magnetic flux. The magnetic flux in thefield cuts the armature to produce a voltage. This voltage is ultimately the output voltage of theAC generator.ArmatureThe armature is the part of an AC generator in which voltage is produced. This componentconsists of many coils of wire that are large enough to carry the full-load current of thegenerator.PrimeMoverThe prime moveris the component that is used to drive the AC generator. The prime mover maybe any type of rotating machine, such as a diesel engine, a steam turbine, or a motor.Rev. 0 Page 1 ES-10
