How An AC Voltage Generator Works

Spread the love

Generators are significant appliances for providing electric energy when power outages occur. It offers continuity of routine activities or business operations through such times.

An ‘electrical voltage generator’ (Also known as ‘เครื่องกำเนิดไฟฟ้า’ in the Thai language) converts mechanical power that’s obtained from an outside source into electric energy output.

They are available in varying physical and electric configurations to suit varied applications and therefore are essential as secondary sources of power in both commercial and industrial settings.

Function Rule of an AC Voltage Generator

Instead, the system uses its own supply of mechanical power for inducing motion of electric charges inside the pipes of its windings through an external electrical circuit.

The flow of electrical charges includes output current which the generator provides. It’s simple to grasp this mechanism by likening the generator into a water pump which allows water to flow through but doesn’t actually create’ it.

The AC voltage generator of the modern day acts on the basis of electromagnetic induction principle, a discovery of Michael Faraday produced between 1831 and 1832.

Faraday found that you can cause the flow of electrical charge explained above by transferring electric conductor such as a cable containing electric charges inside a magnetic field.

The activity subsequently prompts the flow of their electrical charges, thereby producing an electric current.

An electrical generator could be classified into two Major elements as follows:


The motor acts as a source of mechanical power input to the generator and its size changes in direct ratio to the maximum energy output of the AC voltage generator.


The alternator can be termed as aDgenhead’. It’s charged with generating an electrical output signal from mechanical input that the motor supplies.
