The operating principle of the generator set

By knowing how a generator works to power the world, you can be better equipped when it comes to choosing one that will keep your family safe in torrential weather, liven up your next tailgate party or power tools to get the job done.

Generators are everywhere

An electric generator is not just some ubiquitous, utilitarian machine. Instead, generators are the bloodstream that keeps the world humming! Without them, we wouldn't have modern conveniences.

How does a generator work?

Think of a generator as an "energy engine" that converts kinetic energy (motion) into electrical energy. A generator consists of a stationary magnetic field (stator) in which a rotating electromagnet (armature) spins to generate electricity.

In the case of a gasoline-powered generator, an internal combustion engine drives a rotating shaft, thus rotating the armature. In the case of renewables, wind and water, for example, natural forces set the turbine in motion. If you think about it, any kind of motion and therefore energy can be converted into electricity - quite like cranking flashlights.

• Frame - a cover for electrical and moving parts. It protects against dirt and moisture.

• Rotating shaft - connected to the engine or propellers in wind/water generators.

• Bearings - reduces friction caused by rotation.

• Field winding - A coil that produces a magnetic field through which current flows.

• Armature - Produces electromagnetic induction by spinning opposing magnetism inside the stator.

• Stator - A stationary magnetic field with large copper windings.

• Commutator - The conductor through which electricity is drawn.

• Brush assembly - rubs against the commutator, which sends an electric current.

Generator (generator) vs alternator (alternator)

"Many people ask: "What is the difference between an electric generator and an alternator?"

Despite the similarity in design and principle, there are several differences:

(a) The most significant difference is the design. While generators have a fixed magnetic field in which a conductor rotates to produce electromagnetic induction, the entire magnetic field of an alternator rotates while its conductors remain stationary.

(b) Alternators can be powered by both direct current and alternating current. Alternators are usually made for AC (alternating current) applications, hence the name "alternator."

(c) Inherent design differences allow generators to produce huge amounts of energy per kilowatt-hour, and are therefore much more substantial. Similarly, alternators are more economical, use fewer parts and are used in smaller loads, such as cars.

But doesn't the alternator go inside the generator? Type. Sometimes "alternator" generally refers to the combination of rotor and stator as a part, rather than a stand-alone alternator.
