A ship alternator transforms mechanical energy into alternating current electrical energy. NauticExpo offers different types of alternator, including synchronous, asynchronous and triphase.
Alternators are used to produce electricity. They can be driven by an auxiliary engine, a generator or directly by the propeller shaft.
Alternators consist of a stator and a rotor. The stator is a stationary element made up of conductors wound in coils. The rotor is a rotating magnet driven by an outside source of mechanical energy. As it turns, it induces an alternating current in the stator. Rotors can have flat or salient poles.
Choice of alternator will depend on the drive engine, since the number of rotor poles is determined by its rotational speed, measured in revolutions per minute (RPM).
