WebThe automatic drive controls the alternator’s rotational speed which allows the alternator to maintain a constant 400-Hz AC output. All AC alternators must rotate at a specific rpm to keep the frequency of the AC voltage within limits. Aircraft AC alternators should produce a frequency of approximately 400 Hz. An Alexanderson alternator is a rotating machine invented by Ernst Alexanderson in 1904 for the generation of high-frequency alternating current for use as a radio transmitter. It was one of the first devices capable of generating the continuous radio waves needed for transmission of amplitude modulated … Ver mais Prior developments After radio waves were discovered in 1887, the first generation of radio transmitters, the spark gap transmitters, produced strings of damped waves, pulses of radio waves which died … Ver mais A large Alexanderson alternator might produce 500 kW of output radio-frequency energy and would be water- or oil-cooled. One such machine had 600 pole pairs in the stator winding, and the rotor was driven at 2170 RPM, for an output frequency near 21.7 … Ver mais • Alexanderson Day • Tonewheel • Resolver (electrical) Ver mais • "The World's Greatest Wireless Station" (Radio Central), The Book of Radio by Charles Taussig, pages 312-327. • "American Marconi Station, Marion, MA" Ver mais The Alexanderson alternator works similarly to an AC electric generator, but generates higher-frequency current, in the very low frequency (VLF) radio frequency range.

Most power generation stations use synchronous machines as their generators. Connection of these generators to the utility grid requires synchronization conditions to be met. Alternators are used in modern internal combustion engine automobiles to charge the battery and to power the electrical system when its engine is running.
