William Sturgeon (/ ˈ s t ɜːr dʒ ə n /; 22 May 1783 – 4 December 1850) was an English physicist and inventor who made the first electromagnet and the first practical electric motor. Early life [ edit ]
But in 1914 when D. D. Sturgeon-founder of Sturgeon Electric-wanted to give his ill son some Christmas joy, he wrapped his pine trees with electric bulbs, which were dipped in red and green paint.
Hungarian, physicist and unsung father of the dynamo and electric motor; invented the first commutated rotary electromechanical machine with electromagnets. [ 3 ] [ 5 ] He invented the commutator . In 1828, Jedlik demonstrated the first device to contain the three main components of practical DC motors: the stator , rotor and commutator.
Sturgeon (from Old English ... The sturgeons' electroreceptors are located on the head and are sensitive to weak electric fields generated by other animals or ...
Danish scientist Hans Christian Ørsted discovered in 1820 that electric currents create magnetic fields. In the same year, the French scientist André-Marie Ampère showed that iron can be magnetized by inserting it in an electrically fed solenoid. British scientist William Sturgeon invented the electromagnet in 1824.
William Sturgeon built an electric motor in 1832 and invented the commutator, a ring of metal-bristled brushes which allow the spinning armature to maintain contact with the electric current and changed the alternating current to a pulsating direct current. He also improved the voltaic battery and worked on the theory of thermoelectricity.
The Sturgeon class (known colloquially in naval circles as the 637 class) was a class of nuclear-powered fast attack submarines in service with the United States Navy from the 1960s until 2004. They were the "workhorses" of the Navy's attack submarine fleet throughout much of the Cold War .
