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.
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 "; [ 18 ] in 1889 he renamed it the "Westinghouse Electric ...
The first electromagnetic generator, the Faraday disk, was invented in 1831 by British scientist Michael Faraday. Generators provide nearly all the power for electrical grids . In addition to electricity- and motion-based designs, photovoltaic and fuel cell powered generators use solar power and hydrogen-based fuels, respectively, to generate ...
The three also invented the modern power distribution system: Instead of former series connection they connect transformers that supply the appliances in parallel to the main line. The first demonstrative long-distance (34 km, 21 mi) AC line was built for the 1884 International Exhibition of Turin, Italy.
The war of the currents was a series of events surrounding the introduction of competing electric power transmission systems in the late 1880s and early 1890s. It grew out of two lighting systems developed in the late 1870s and early 1880s; arc lamp street lighting running on high-voltage alternating current (AC), and large-scale low-voltage direct current (DC) indoor incandescent lighting ...
"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 ...
Kettering was hired directly out of school to head the research laboratory at National Cash Register (later known as NCR Corporation). Kettering invented an easy credit approval system, a precursor to today's credit cards, and the electric cash register in 1906, which made ringing up sales physically much easier for sales clerks.
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.
