A device that converts mechanical energy into electrical energy. The alternator is also referred to as the gen end. Brushless alternators are often used in large generators, while permanent magnets ar [..]

Current flow of electric charge that periodically reverses direction, typically 50 or 60 Hz.

A national service organization that represents 2000 municipal and other state or local publicly owned electric utilities spread across the United States.

Measurement of the strength or intensity of an electric current in ampere.

A mechanical device that switches an electrical load from a preferred source, usually a utility service, to an alternate source, usually an emergency generator. It also incorporates controls to start [..]

A stand-by source of energy used to fill emergency load requirements during a sudden shortage or loss of power. Backup generators are usually diesel engine driven and can turn on automatically during [..]

This component changes AC voltage from the battery charge windings to DC voltage for charging a battery. This is found only on very small generators.

Sudden or unexpected disruption of electrical power.

Brushes are typically made of graphite or copper, they are conducting elements that maintain sliding electrical contact between static and moving elements. In order for a generator to function, brushe [..]

The core, also known as the stator core, is a stacked laminated cylindrical structure in a generator.
