HOW A DIESEL GENERATOR WORKS

Our world revolves around energy. At Doosan portable power, powering productivity is our business. We specialize in building products that put power to work out mobile generators transform the stored energy and diesel fuel to electricity for daily use. Let us take a closer look at a generator engine that converts diesel fuel to mechanical energy that rotates the crankshaft as combustion occurs in each cylinder. Energy transmits to the engine crankshaft, which generates mechanical power for the alternator. An alternator converts mechanical power into electrical energy in a process called magnetic induction. Magnetic induction occurs when a conductive material such as a copper wire passes through a magnetic field, and voltage is produced if the wire is connected in a complete circuit, the power can be transmitted. Alternators include two primary parts, a stator, and a rotor. The stator contains copper coils wound into the alternator’s outer casing. The rotor also has wire coils wrapped around an iron core, but unlike the stator, it is attached to the engine crankshaft, so it rotates with the engine. When voltage passes through the rotor coils, it creates an electromagnetic field. As the rotor spins, its magnetic field cuts across the stator’s conductive wire and generates voltage because the magnetic field builds and subsides voltage fluctuates between positive and negative peaks. This is known as alternating current—the more robust the field, the higher the peaks. Ideally, voltage levels should be consistent so that constant power is provided when under load to do. So an automatic voltage regulator or AVR adjusts the magnetic fields as needed during heavy power demands voltage decreases, causing the AVR to increase the magnetic field; conversely, when power demands are low, the AVR tempers the field. Doosan mobile generators also include alternators with six coils wound into the stator. This provides three voltage sources or phases because each phrase combines two coins of wire. The sources can be connected in series for high voltage applications or in parallel for low voltage needs to simplify wire connections. Doosan mobile generators have a convenient selector switch. When an operator selects the desired voltage, the switch adjusts the connections, and current flows through a protective device called a circuit breaker. If the current exceeds capacity, the breaker halts the system protecting the generator and connected equipment from potential damage. Once power reaches the connection panel, operators can attach power cables to the generator’s terminal board receptacle panel or cam lock panel, transforming electrical energy into light heat or motion, providing the power we rely on every day.
