Early electric motor,1834
Early electric motor. Historical artwork of one of the first full-scale,practical electric motors,one of several designed and built from 1834 by the German physicist and engineer Moritz von Jacobi (1801-1874). The principle of the electric motor had been demonstrated by Michael Faraday in 1821. Jacobi moved to St Petersburg,Russia,in 1837. In 1839,financed by Tsar Nicholas I,he built a boat that used electric batteries to power an electric motor to drive paddlewheels. A similar arrangement is seen here,with wires (bottom) connecting to the batteries,and eight solenoids (wires coiled around cylinders) acting as electromagnets to turn wheels on the central shaft. Artwork from A Travers l'Electricite (G. Dary,Paris,1900)
