"Dynamo Electric Machine" (end view, partly section, U.S. patent 284,110) A dynamo is an electrical generator that creates direct current using a commutator.Dynamos were the first electrical generators capable of delivering power for industry, and the foundation upon which many other later electric-power conversion devices were based, including the electric motor, the alternating-current ...
A Gramme machine or Gramme magneto. A Gramme machine, Gramme ring, Gramme magneto, or Gramme dynamo is an electrical generator that produces direct current, named for its Belgian inventor, Zénobe Gramme, and was built as either a dynamo or a magneto. [1] It was the first generator to produce power on a commercial scale for industry.
Wilde invented the dynamo-electric machine, or self-energising dynamo, an invention for which Werner von Siemens is more usually credited and, in fact, discovered independently. At any rate, Wilde was the first to publish, [ 4 ] his paper was communicated to the Royal Society by Michael Faraday in 1866.
U.S. patent 334,823 - Commutator for Dynamo Electric Machines - 1886 January 26 - Elements to prevent sparking on dynamo-electric machines; Drum-style with brushes.; U.S. patent 335,786 - Electric Arc lamp - 1886 February 9 - Arc lamp with carbon electrodes controlled by electromagnets or solenoids and a clutch mechanism; Corrects earlier design flaws common to the industry.
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.
The Gramme machine was the first usefully powerful electrical motor that was successful industrially. Before Gramme's inventions, electric motors attained only low power and were mainly used as toys or laboratory curiosities. In 1875, Nikola Tesla observed a Gramme machine at the Graz University of Technology.
Dividend investing is a tried-and-true strategy for generating strong, steady returns in economies both good and bad. But as corporate America's slew of dividend cuts and suspensions over the past ...
Werner von Siemens, ennobled in 1888, developed an electric generator, based on the dynamo-electric principle, which he patented in 1866. On January 17, 1867, he gave a lecture before the Berlin Academy of Sciences, in which he provided the first scientific description of the dynamo-electric principle. Based on these foundations, electric ...
