Generators serve as fantastic backup devices, especially during hot summer days when power outages occur frequently. Do you know what generators are? Are you aware of the various types of generators available in the market today? If not, let's explore them below with Mytour.
1. What is a Generator?
What is a Generator?
Generators transform mechanical energy into electrical energy, providing temporary power to other devices in case of power loss. The majority of the mechanical energy for generators is derived from gasoline, diesel, or natural gas.

Understanding the Role of Generators
Generators play a crucial role in both daily life and production. They produce electrical energy, meeting the demand for electricity in situations like power shortages, outages, overloads, etc. Additionally, they serve various useful functions such as power generation, rectification, and voltage regulation.
2. Anatomy of a Generator
A generator consists of the following main components:
- Engine: Provides the mechanical input energy to the generator.
- Generator Head: Produces electricity from the supplied mechanical energy source.
- Fuel System: includes fuel tank, piping system, fuel pump, injector,…
- Voltage Regulator (AVR): regulates the output voltage level of the generator.
- Cooling System: cooled by air fans or water fans.
- Lubrication System: lubricates the engine of the machine with stored lubricating oil in a pump, ensuring better engine performance.
- Exhaust System: exhaust gas emitted from the generator during operation passes through this exhaust pipe.
3. Operational Principle of Generators
The operation principle of a generator relies on the phenomenon of electromagnetic induction. When the generator is active, it causes alternating increases and decreases in the magnetic flux lines passing through the coil's cross-section. This alternating flux induces current in the coil, which also alternates in direction. As a result, electricity is generated.
4. Common types of generators today
To select the most suitable generator for your needs, you need to know the common types of generators available today.
Different types of generators are classified based on the following criteria:
Classification of generators based on the type of fuel used
Generators running on gasoline: They have low power output and are suitable for household, office, or small-scale business use.
Diesel-powered generators: These machines have high power output, making them suitable for large buildings, construction sites, and large offices.
Natural gas-powered generators: Although they have lower power output compared to diesel and petrol generators, they help reduce environmental emissions.
Classification of generators by engine type
The engines in generators are classified into the following types:
Generators' rotational speed: engines running at 3000 rpm and engines running at 1500 rpm.
Arrangement of the engine: vertical generators, horizontal generators.
Cooling system: Cooling by air, cooling by water.
Classification by generator set
Conventional diesel generator set.
Automatic diesel generator set with microprocessor control.
Automatic start diesel generator set.
Classification by power output
Residential generators: Under 10KW.
Industrial generators: Above 10KW.
Classification by usage purpose
Home generators: Used for households during power outages. Generates 220V electricity, providing stable power for household appliances.
Industrial generators: Large capacity machines ensuring stable power for industrial machinery in factories, workshops, etc., without the risk of overload.
Portable generators: Compact design, easy to move, providing power for small energy needs.
Classification based on the number of phases of the output current
Single-phase generators: Operate by generating continuous alternating current, producing single-phase 220V electricity. They have relatively low power and are used in households or small retail stores.
Three-phase generators: Industrial generators with high power output, serving in factories, plants, hospitals, schools, etc., where large power consumption is needed. These generators operate based on the phenomenon of electromagnetic induction.
