Permanent magnet generators (PMGs) or alternators (PMAs) do not require a DC supply for the excitation circuit, nor do they have slip rings and contact brushes. A key disadvantage in PMAs or PMGs is that the air gap flux is not controllable, so the voltage of the machine cannot be easily regulated. A persistent magnetic field imposes safety issues during assembly, field service or repair. High performance permanent magnets, themselves, have structural and thermal issues.

WebMar 30, 2024 · Together, both alternators combined in a small brushless ac generator may present an appearance of a single unit, but you can easily distinguish them as two separate items in larger machines. The excitation for such systems is provided by an auxiliary synchronous generator called an exciter mounted towards the one end of the main … WebThe ratings of synchronous generators for large power systems extend up to about 2,000 megavolt-amperes. Smaller power systems use generators of lower rating (e.g., 50 megavolt-amperes and up) since it is usually not desirable to have more than 10 percent of the total required system generation in one machine.
