Faraday developed the "rotating rectangle", whose operation was heteropolar – each active conductor passed successively through regions where the magnetic field was in opposite directions. The early machines were developed by pioneers such as Michael Faraday and Hippolyte Pixii. Rotating generators naturally produced alternating current but, since there was little use for it, it was normally converted into direct current via the addition of a commutator in the generator. Īlternating current generating systems were known in simple forms from the discovery of the magnetic induction of electric current in the 1830s. This machine was used as a generator producing 3,000-volt, 133-hertz, single-phase AC, and an identical machine 3 miles (4.8 km) away was used as an AC motor. In what is considered the first industrial use of alternating current in 1891, workmen pose with a Westinghouse alternator at the Ames Hydroelectric Generating Plant. 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. Alternators in power stations driven by steam turbines are called turbo-alternators. In principle, any AC electrical generator can be called an alternator, but usually the term refers to small rotating machines driven by automotive and other internal combustion engines.Īn alternator that uses a permanent magnet for its magnetic field is called a magneto. Occasionally, a linear alternator or a rotating armature with a stationary magnetic field is used. For reasons of cost and simplicity, most alternators use a rotating magnetic field with a stationary armature. Īn alternator is an electrical generator that converts mechanical energy to electrical energy in the form of alternating current. But all Valeo products are built to withstand even the harshest conditions and designed to last for years to come.Alternators made in 1909 by Ganz Works in the power generating hall of a Russian hydroelectric station (photograph by Prokudin-Gorsky, 1911). It is also engineered using the latest technology for maximum efficiency, even under hostile operating environments. The Valeo clutch is made to exacting standards to ensure quality, reliability, and performance. Founded in 1923 in Saint Ouen, France, this company has grown immensely, and among its highly acclaimed products is its expansive line of OE and aftermarket clutches, kits, and components. Valeo® has established itself as a leading supplier of thermal, powertrain, and other automotive systems, including the transmission, air conditioning, lighting, electrical, wiping, and cooling and air management.
