History
The idea of a rotating magnetic field was developed by François Arago in 1824, and first implemented by Walter Baily. Based on this, practical alternating current induction motors seem to have been independently invented by Nikola Tesla and Galileo Ferraris. Ferraris demonstrated a working model of his motor in 1885 and Tesla built his working model in 1887 and demonstrated it at the American Institute of Electrical Engineers in 1888 (although Tesla claimed that he conceived the rotating magnetic field in 1882). In 1888, Ferraris published his research to the Royal Academy of Sciences in Turin, where he detailed the foundations of motor operation; Tesla, in the same year, was granted a United States patent for his own motor. The modern system of a three-phase transformer and induction motor with a cage was invented by Mikhail Dolivo-Dobrovolsky in 1889/1890.
