The four alternating current generators are some of the most powerful rotating armature 3-phase machines ever built. Newly invented by Elihu Thomson, they weighed almost 30 tons each (57,887 pounds) and were 8.5-foot-tall (2.6 m). These original AC generators used many DC generator components in their first design.
The demonstration lighting system was driven by a hydroelectric generator that produced 500 volts AC, which was then stepped down to 100 volts to light incandescent bulbs in homes and businesses. That same year, Westinghouse founded the " Westinghouse Electric & Manufacturing Company "; [ 20 ] in 1889 he renamed it the "Westinghouse Electric ...
Today a large proportion of steam turbine generators operating around the world, ranging to units as large as 1,500 MW (or 1,000 times the original 1901 unit) were supplied by Westinghouse from its factories in Lester, Pennsylvania, Charlotte, North Carolina, or Hamilton, Ont. or were built overseas under Westinghouse license.
Manfred von Ardenne invented and developed the flying-spot scanner, Europe's first fully electronic television camera tube. In Britain, the first television advertising and the first TV interview; 1931 The British engineer and inventor Alan Dower Blumlein (1903–1942) invents "Binaural Sound", today called "Stereo".
Founded by Robert Kern in 1959, the company soon began producing portable generators for Sears, Roebuck and Co. under the Craftsman brand. During the 1970s, Generac expanded its offerings in the portable and recreational vehicle markets, and in the 1980s the company entered the commercial and industrial markets with its backup power generation systems.
Generators produce nearly all of the electric power for worldwide electric power grids. The first electromagnetic generator, the Faraday disk, was invented in 1831 by British scientist Michael Faraday. The reverse conversion of electrical energy into mechanical energy is done by an electric motor, and motors and generators are very similar ...
U.S. patent 2,475,841 was issued on July 12, 1949 – Automatic refrigeration system for long-haul trucks. U.S. patent 2,475,842 was issued on July 12, 1949 – Starter generator. U.S. patent 2,475,843 was issued on July 12, 1949 – Means operated by a starter generator for cooling a gas engine.
He invented the first AC motor in 1885. After him, the German engineer Friedrich August Haselwander develops the first AC 3 phase synchronous generator in Europe which produced about 2.8 kW at 960 rev/min, corresponding to a frequency of 32 cycles per second, today known as Hertz, or Hz.
