Alternator:

An alternator is an electromechanical device that by a rotating magnetic field converts mechanical energy to electrical energy, inducing an AC voltage in the stator windings.

Domains of application:

Every field that requires electricity generation with various functioning parameters (voltage, frequency, electric power).

Classification of alternators:

CC alternators with:

• independent excitation
• derivation excitation
• serial excitation
• compound excitation

Asincronous alternators with:

• rotating winding and collecting rings
• scurtcircuited rotor

Sincronous alternators

• normal construction, armature in stator and inductor in rotor
• inverse construction, armature in rotor and inductor in stator

Special alternators:

• welding generators
• high frequency generators
• amplidines, etc.

According to the theory of reversibility of electric machines, generally, an alternator can function as an electric engine, too.
