Electric motors have a long history going back to the early nineteenth century.

Nineteenth century
Date, Name Electric Motor Chronology Selected Patents
1740s, Andrew Gordon and Benjamin Franklin British (Gordon), American (Franklin); experimentation with electrostatic motors.[1][2]
1820, Hans Christian Ørsted Danish, physicist and chemist; first to note a compass needle deflected from magnetic north when an electric current from a battery was switched on and off, confirming a direct relationship between electricity and magnetism.[3][4][5][6]
1820, André-Marie Ampère French, physicist; invented the solenoid.[3][6]
1821 Michael Faraday British, scientist; showed continuous 'electromagnetic rotation' resulted by suspending a magnetic wire in an electric field;[3][4][5][6]
1822, Peter Barlow British, physicist; invented Barlow's wheel, the first device ever powered by electromagnetism.[3][5][6][7]
1824, François Arago French, physicist; showed a rotating copper disk produced rotation in a magnetic needle suspended above it, which Faraday later attributed to induction phenomena.[6][8][9]
1828, Ányos Jedlik 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.[10][11][12][13][14][15][16]
Before 1830, Johann Michael Ekling Austrian, mechanic; constructed an electric motor according to the plans of Austrian physicist Andreas von Baumgartner.[17]
1831 Michael Faraday British, scientist; discovered and investigated induction law in terms of electric current generation in a varying magnetic field.[3][5][6][18]
1831, Joseph Henry American, physicist; Created a mechanical rocker, which he however describes as a philosophical toy.[3][6][18]
1825-1833 William Sturgeon British, scientist; 1825 - invented the electro-magnet; 1833 - built first commutated rotating electric machine that was demonstrated in London.[3]
1832–33, Hippolyte Pixii French, instrument maker, built the first AC generating apparatus out of a rotation; and, the following year, an oscillating DC generator.[3][5][6][19]
1833, Joseph Saxton American, inventor; demonstrated a magneto-electric machine before the British Association for the Advancement of Science.[18]
1833, Heinrich Friedrich Emil Lenz German; formulated the law of reversibility of generators and motors.[3][4][6]
1834–1839, Moritz von Jacobi German-Russian, engineer and physicist; built a 15 watt motor in 1834 submitted to the Academy of Sciences in Paris with details published in 1835; demonstrated first use of electric motor to propel a boat; first real useful rotary electrical motor.[3][5][6][18][20]
1837, Thomas Davenport and Emily Davenport American, blacksmith-inventor and inventor; obtained first US electric motor patent.[3][5][7][18] US 132
1837–1842, Robert Davidson Scottish, inventor; developed electric motors for a lathe and a locomotive.[3][5][18][20]
1838, Solomon Stimpson American; built a 12-pole electric motor with segmental commutator.[7][18][20] US 910
1840, Truman Cook American; built electric motor with a PM armature.[18][20] US 1735
1845, Paul-Gustav Froment French, engineer and instrument maker; first of various motors; first motor translated linear "electromagnetic piston's" energy to wheel's rotary motion. See also Mouse mill motor.[6][18][20][21]
1856, Werner Siemens German, industrialist; invented generator with a double-T armature and slots windings.[3][6]
1861–1864, James Clerk Maxwell British, scientist; reduced electromagnetism knowledge in four key equations.[3][5][6]
1871–1873, Zénobe Théophile Gramme Belgian, engineer; developed the anchor ring motor which solved the double-T armature pulsating DC problem; at Vienna exhibition, demonstrated to great effect ability to transmit between generator and motor 1 km apart.[3][6]
1879, Walter Baily British; based on Arago's rotations, by manual switching on and off, developed the first primitive commutatorless induction motor.[4][9]
1880, Marcel Deprez French engineer; by the progressive shifting of a magnetic field through the mechanical commutator in regular order around a center, electric currents are being developed by induction in a rotating metal mass without sliding contacts or commutator.[22]
1885, Galileo Ferraris Italian, physicist and engineer; invented the first AC commutatorless induction motor using two-phase AC windings in space quadrature. Delivered a paper on it in April 1888.[3][4][9][23]
1887, M. Borel Constructed a two phase motor where the rotor is set in rotation by the combined rotating field produced with two set's 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]
1887, Charles S. Bradley Motor/generators with a Gramme ring, having multiple radial connectors, led off at corresponding symmetrical points to slip-rings. He thus obtained alternate currents differing in phase.[26] US390439A
1887–1891, Nikola Tesla Serbian-American, engineer and inventor; having worked independently from Ferraris, presented a paper in May, 1888 to AIEE describing three patented two-phase four-stator-pole motor types: one with a four-pole rotor forming a non-self-starting reluctance motor, another with a wound rotor forming a self-starting induction motor, and the third a true synchronous motor with separately-excited DC supply to rotor winding. Westinghouse acquired exclusive rights to the Tesla patents as well as the Ferraris design and retain Tesla as a consultant for a short time to work on development of these motors.[3][4][5][6][9] US 0,381,968
US 0,381,969
US 0,382,279
US 0,382,280
1886, Frank Julian Sprague American, industrialist; development of new constant-speed DC motor, which allowed the Sprague company to issue the world's "first important industrial electric motor catalogue".[27]
1889–90, Mikhail Dolivo-Dobrovolsky Polish-Russian, engineer and inventor; invented the first cage and wound rotor versions of the three-phase induction motor that are still widely in use today.[3][4][5][6][9]
