How do power generators work?

Industrial-sized power generators are used for a range of applications across a wide scope of industries. Diesel-powered generators possess numerous benefits, especially when working in isolated locations due to their robust reliability.

Renteca offers a premium selection of compliant performance-ready certified power generators for hire to support a range of projects including mine site and power station shutdowns, pipeline or tank construction and other short and long-term projects across Australia, New Zealand, Papua New Guinea and Asia.

Renteca’s power generators are a vital part of each job and are available from 25kva up to a hefty 550kva. With a catalogue of leading brands available, including Caterpillar and Imnesol, you may wonder about their operating capacity and technical engineering, including how magnets are used in generators.

How are magnets are used in generators?

Basic principles of physics explain that the properties of a magnet’s push and pull electrons can generate electricity. Power generators are based on this precise connection between magnetism, motion and electricity.

For example, moving a magnet around a conductor such as a coil of wire forcibly pushes the electrons within that wire. This is a form of kinetic energy which, via motion, creates an electrical current through a magnetic field. Formally known as induction, increased voltage is produced when the magnets are stronger and when more turns of wire in the coil are added, therefore increasing the motion of each component.

How magnets are used in generators specifically is based on these fundamentals with the added power of rotating equipment such as a turbine used to maximise mechanical motion and, therefore, power output. A turbine’s rapid rotation utilises the kinetic energy of a fuel source such as water, steam, air, combustion gases, or diesel, and turns this into the revolving movement of the device itself.

With turbines spinning at high speeds thanks to their partnership with magnets and a fuel source, power generators can harvest the optimal amount of kinetic energy required to convert to electricity energy. The mechanical composition of a generator unit is engineered to facilitate these rapid electrical charges, forcing electricity through wiring as a power resource.

The massive amounts of current surging through industrial sized power generators has the capability to uphold electricity in a range of applications including for recreational activities, in isolated residential locations, as back-up power during disasters or emergencies, or on site in the mining, construction, agriculture and transport industries, plus more.
