Timeline of the electric motor
Electric motors have a long history going back to the early 19th century.
|Date, Name||Electric Motor Chronology||Selected Patents|
|1820, 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.|
|1820, Ampère||French, physicist; invented the solenoid.|
|1821 Faraday||British, scientist; showed continuous 'electromagnetic rotation' resulted by suspending a magnetic wire in an electric field;|
|1822, Barlow||British, physicist; invented Barlow's wheel, the first device ever powered by electromagnetism.|
|1824, Arago||French, physicist; showed a rotating copper disk produced rotation in a magnetic needle suspended above it, which Faraday later attributed to induction phenomena.|
|1828, Jedlik||Hungarian, physicist and unsung father of the dynamo and electric motor; invented the first commutated rotary electromechanical machine with electromagnets.|
|1831 Faraday||British, scientist; discovered and investigated induction law in terms of electric current generation in a varying magnetic field.|
|1831, Henry||American, physicist; Created a mechanical rocker, which he however describes as a philosophical toy.|
|1825-1833 Sturgeon||British, scientist; 1825 - invented the electro-magnet; 1833 - built first commutated rotating electric machine that was demonstrated in London.|
|1832-33, Pixii||French, instrument maker, built the first AC generating apparatus out of a rotation; and, the following year, an oscillating DC generator.|
|1833, Saxton||American, inventor; demonstrated an magneto-electric machine before the British Association for the Advancement of Science.|
|1833, Lenz||German; formulated the law of reversibility of generators and motors.|
|1837, Davenport||American, blacksmith-inventor; obtained first US electric motor patent.||US 132|
|1838, Solomon Stimpson||American; built a 12-pole electric motor with segmental commutator.||US 910|
|1834-39, Jacobi||Russian, engineer and physicist; built a 15 watt motor in 1834 submitted to the Academy of Sciences in Paris with detailes published in 1835; demonstrated first use of electric motor to propel a boat; first real useful rotary electrical motor.|
|1840, Truman Cook||American; built electric motor with a PM armature.||US 1735|
|1837-42, Davidson||Scottish, inventor; developed electric motors for a lathe and a locomotive.|
|1845, 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.|
|1856, Siemens||German, industrialist; invented generator with a double-T armature and slots windings.|
|1861-64, Maxwell||British, scientist; reduced electromagnetism knowledge in four key equations.|
|1871-73, Gramme||Belgium, 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.|
|1879, Walter Baily||British; by manual switching on and off, developed the first primitive commutatorless induction motor.|
|1885, Ferraris||Italian, physicist and engineer; invented the first AC commutatorless induction motor using two-phase AC windings in space quadrature.|
|1886-89, Tesla||Serbian-American, engineer and physicist; having worked independently from Ferraris, presented a key paper in 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. This led to Westinghouse acquiring exclusive rights to him patents and retain him as a consultant to work on development of these motors.||US 0,381,968
|1886, 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".|
|1889-90, Dolivo-Dobrovolsky||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.|

|1905, Alfred Zehden||A feasible linear induction motor described in patent form for driving trains or lifts.||U.S. Patent 782,312|
|1935, Kemper||Built a working linear induction motor|
|1945-49, Laithwaite||First full-size working model of linear induction motor|
