How Cummins Onan Generators Work
At their core, Cummins Onan generators convert fuel energy into electrical energy. Here is a simple explanation of the process:
- Fuel Combustion: The generator engine burns fuel, usually gasoline, diesel, or propane, to create mechanical energy.
- Mechanical to Electrical Energy Conversion: The engine drives a rotor inside an alternator, which spins within a magnetic field.
- Electricity Generation: The spinning rotor induces an electrical current in the stator coils of the alternator.
- Power Output: The electricity is then regulated and sent to the generator’s output terminals, ready to power electrical equipment.
This process allows Cummins Onan generators to deliver reliable and continuous power whenever needed.
Applications of Cummins Onan Generators
