Generators

Generators are machines that convert mechanical energy into electric energy. Operating on the principle of electromagnetic induction, generators were first discovered by M. Faraday in the 1830's. In any generator, the entire assembly carrying the coils is called the armature, or rotor, while the stationary parts constitute the stator. The generator rotor is turned by a device called a prime mover, which may be an engine, steam turbine, water turbine or other medium coupled to the rotor shaft.

Some of the smallest generators commonly found are used to power bicycle lights, whereas the greatest amount of electricity for industrial and civilian use comes from large AC (alternating current) generators driven by steam turbines. Aircraft have switched from DC (direct current) generators to alternators that are typically powered by a takeoff from an engine. Sailing yachts may use a water or wind powered generator to trickle-charge the batteries.

Generators are used to perform a wide variety of tasks, thus there are many models to choose from to suit all needs. For example, generators of varying amounts of power are needed for: Camping/Recreation/Boating; Home Appliances; Construction. Some of the top manufacturers of generators include: Honda, Yamaha, Kohler, Generac and Coleman.

As power demand continues to outpace available power resources worldwide, blackouts and rolling brownouts are common. Power failures can wreak havoc on your home and business, hence the importance today of a quality backup power generator. Like all consumer goods, the quality of your generator probably will depend on the amount of money you spend. Portable generators can be purchased for a few hundred dollars, but top-of-the-line standby generators likely will cost you thousands, not including maintenance costs. Used generators are another option.

When buying a generator, you need to consider how you plan to use it. Be sure to purchase the correct size generator for your needs and carefully follow all manufacturers instructions regarding proper grounding and total electric load. Experienced generator dealers are an excellent source of guidance and consultation.

Here are some safety considerations you should follow when powering home appliances: Generators must operate outdoors - not in a garage - and as far away as reasonably possible because they produce poisonous exhaust. Further, keep your generator dry and always operate it on a level surface. Never add fuel to your generator when it is running and always store additional fuel in approved gasoline containers. Before storing, make sure the fuel valve is turned OFF. If left on, gasoline may get into the engine crankcase and dilute the engine oil, thus reducing the lubrication properties of the oil and causing severe engine damage. Store in a safe place.
