Worldwide Power Products features a wide selection of new and used generator ends from manufacturers such as Marelli Motori, Caterpillar, and Kato.

A generator end (also called alternator) houses electrical conductors which react to the engine's mechanical energy and convert it into useful electrical power. A generator's output of electrical power is measured in kilowatts.

In principle, any AC electrical generator can be called a generator end (alternator) but usually the term refers to small rotating machines driven by automotive and other internal combustion engines. Here are some informative articles on generator ends and their application.

A generator set combines two components to form a single power generation equipment. It is often referred to a generator or a genset. The front part is the engine that provides the power to the unit. The engine can run on a variety of fuel sources, most notably natural gas, gasoline or diesel.

The critical back portion of the genset is the generator end which provides the electric energy for creating power. The generator size can cover a large range, from as small as 10 kW to as large as 10 MW or beyond. The combined unit can be supplied as mobile, standby or fixed. Mobile units are often trailer mounted for temporary or emergency use.

These major genset components need to be reliable, robust and capable of working in a variety of climates and operating conditions. That is where Marelli generators and Worldwide Power Products stand out.
