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 (kW).


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 diesel or natural gas.

The critical back portion of the genset is the generator end (or alternator) 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.

These major genset components need to be reliable, robust and capable of working in a variety of climates and operating conditions.  That is where manufacturers like Marelli, Cat and Kato generators truly stand out.
