Know About How does a Generator Work

Within the realm of electricity generation, generators are an invention that has radically changed our ability as a society to create and harness electrical currents for everyday use. Generators are devices that produce electrical power through the conversion of mechanical energy, and common types include steam turbines, wind turbines, internal combustion engines, hand cranks and much more. As Electrical Generators serve such an important purpose to our modern society and provide power for much of what we rely on, understanding how they function and being aware of the various parts that make them up is very important.

One of the most important concepts to understand about generators is that they do not create their own electricity, rather they utilize mechanical energy to move electrical charges within their winding to create a current. While various electrical generator sets may vary from type to type, the most common components implemented include those such as engines, alternators, fuel systems, Voltage Regulators, cooling and exhaust systems, battery chargers, control panels, and a main assembly or frame.

The engine is highly important as it serves as the input for the mechanical energy as well as dictates the amount of power that the generator can produce based on its size. Typically, electrical generator sets will utilize various types of fuel to drive the engine, such as diesel or propane, and valves allow for the escape of exhaust. The alternator is then the generator section that produces the electrical output by harnessing the mechanical input that is supplied by the engine. To create electrical current, the alternator will often feature a number of stators that serve as electrical conductors and armatures which generate a rotating magnetic field through induction, permanent magnets, or by utilizing an exciter. Through the interaction of these components, relative movement between the electric fields and magnetic fields cause electricity to be generated. Within the alternator, a Generator Bearing Assembly will also be present to facilitate motion and protect parts from stressors.

To ensure that the engine can produce sufficient mechanical power for the alternator to harness, electrical engine sets require a fuel system. These units may be internal or external to the generator depending on the application and size, and common features of the fuel tank system include pipe connections, ventilation pipes, overflow connections, Fuel Pumps Assembly, fuel filters, and fuel injectors to ensure that fuel moves throughout the system efficiently as well as is contained and exhausted correctly. Cooling and exhaust systems aid in this endeavor through venting heat and exhaust, allowing the apparatus to maintain a cool enough temperature to avoid damages and to protect surrounding individuals from harmful gases. Through the operation of the generator, the lubricating system proves useful for the durability of the many moving generator parts.


In the present day, many modern generators will often feature a starter function that is controlled by batteries, and thus a battery charger is critical for the operation of a modern Electrical Generator Set so that the generator battery is supplied with a float voltage. Many of these battery chargers are fully automatic, allowing an ease of operation. Modern generators also often feature control panels, allowing for operators to start, shut down, and guage the performance of the engine.
