EASA Module 3 Electricity:
ALTERNATORS & CLASSIFICATIONS An electrical generator is a machine, which converts mechanical energy into electrical energy by electromagnetic induction. A generator which produces alternating current is referred to as an AC generator and, through combination of the words “alternating” and “generator,” the word “alternator” has come into widespread use easa module 3 electricity.
In some areas, the word “alternator” is applied only to small AC generators. This text treats the two terms synonymously and uses the term “alternator” to distinguish between AC and DC generators. The major difference between an alternator and a DC generator is the method of connection to the external circuit; that is, the alternator is connected to the external circuit by slip rings, but the DC generator is connected by a commutator easa module 3 electricity.
METHOD OF EXCITATION One means of classification is by the type of excitation system used. In alternators used on aircraft, excitation can be affected by one of the following methods: 1. A direct connected, direct current generator. This system consists of a DC generator fixed on the easa module 3 electricity
