William Sturgeon (/ ˈ s t ɜːr dʒ ə n /; 22 May 1783 – 4 December 1850) was an English electrical engineer and inventor who made the first electromagnet and the first practical electric motor. Early life
A DC motor is an electrical motor that uses direct current (DC) to produce mechanical force. The most common types rely on magnetic forces produced by currents in the coils. Nearly all types of DC motors have some internal mechanism, either electromechanical or electronic, to periodically change the direction of current in part of the motor.
Constructed a two-phase motor where the rotor is set in rotation by the combined rotating field produced with two sets of coils. [24] 1887, Helios Co. Based on Coerper's patent, Helios Co. constructed the first 3-phase motor with three slip-rings. The project was dropped in 1890 as they could get satisfactory results using a 2-phase current. [25]
The first commutator DC electric motor capable of turning machinery was invented by the British scientist William Sturgeon in 1832. [75] The crucial advance that this represented over the motor demonstrated by Michael Faraday was the incorporation of a commutator. This allowed Sturgeon's motor to be the first capable of providing continuous ...
The first commutator DC electric motor capable of turning machinery was invented by English scientist William Sturgeon in 1832. [23] Following Sturgeon's work, a commutator-type direct-current electric motor was built by American inventors Thomas Davenport and Emily Davenport, [24] which he patented in 1837.
A brushed DC electric motor is an internally commutated electric motor designed to be run from a direct current power source and utilizing an electric brush for contact. Brushed motors were the first commercially important application of electric power to driving mechanical energy, and DC distribution systems were used for more than 100 years ...
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.
Joseph Henry (December 17, 1797 [1] [2] – May 13, 1878) was an American experimental physicist and inventor who served as the first secretary of the Smithsonian Institution.
