2. Alternator - Wikipedia

   en.wikipedia.org/wiki/Alternator

   An alternator that uses a permanent magnet for its magnetic field is called a magneto. Alternators in power stations driven by steam turbines are called turbo-alternators. Large 50 or 60 Hz three-phase alternators in power plants generate most of the world's electric power, which is distributed by electric power grids. [4]

3. Magneto - Wikipedia

   en.wikipedia.org/wiki/Magneto

   By the late 1980s, developments in magnetic materials such as samarium–cobalt, an early rare-earth type, let permanent magnet alternators be used in applications that require an extremely robust generator. In guided missiles, such generators can replace a flux switching alternator. [15]

4. Automobile accessory power - Wikipedia

   By regulating the current sent to the alternator's rotor and thus the strength of the magnetic field, a stable voltage can be produced over a wider range of engine speeds. Starting, lighting and ignition systems of most gasoline-powered vehicles remain as 12 volt systems.

5. Excitation (magnetic) - Wikipedia

   en.wikipedia.org/wiki/Excitation_(magnetic)

   Alternator of 1930s diesel generating set, with excitation dynamo above. For large, or older, generators, it is usual for a separate exciter dynamo to be powered in parallel with the main power generator. This is a small permanent-magnet or battery-excited dynamo that produces the field current for the larger generator.

6. Electric generator - Wikipedia

   en.wikipedia.org/wiki/Electric_generator

   A generator using permanent magnets (PMs) is sometimes called a magneto, or a permanent magnet synchronous generator (PMSG). Armature: The power-producing component of an electrical machine. In a generator, alternator, or dynamo, the armature windings generate the electric current, which provides power to an external circuit.

7. Alternator (automotive) - Wikipedia

   en.wikipedia.org/wiki/Alternator_(automotive)

   Larger permanent magnet electric machines (that can operate as motors or alternators) can achieve today much higher efficiencies. Pellegrino et al., [12] for instance, propose not particularly expensive designs that show ample regions in which efficiency is above 96%. Large AC generators used in power stations run at carefully controlled speeds ...
