who developed the first induction motor that was an alternating current power system?
nikola tesla
one of westinghouse's engineers, william stanley, recognised the problem with connecting transformers in series as opposed to parallel and also realised that making the iron core of a transformer a fully enclosed loop would improve the voltage regulation of the secondary winding. using this knowledge he built the world's first practical transformer based alternating current power system at great barrington, massachusetts in 1886. in 1885 the italian physicist and electrical engineer galileo ferraris demonstrated an induction motor and in 1887 and 1888 the serbian-american engineer nikola tesla filed a range of patents related to power systems including one for a practical two-phase induction motor which westinghouse licensed for his ac system.

george westinghouse, who was developing an alternating current power system at that time, licensed tesla’s patents in 1888 and purchased a us patent option on ferraris' induction motor concept. tesla was also employed for one year as a consultant. westinghouse employee c. f. scott was assigned to assist tesla and later took over development of the induction motor at westinghouse. steadfast in his promotion of three-phase development, mikhail dolivo-dobrovolsky invented the cage-rotor induction motor in 1889 and the three-limb transformer in 1890. furthermore, he claimed that tesla's motor was not practical because of two-phase pulsations, which prompted him to persist in his three-phase work. although westinghouse achieved its first practical induction motor in 1892 and developed a line of polyphase 60 hertz induction motors in 1893, these early westinghouse motors were two-phase motors with wound rotors until b. g. lamme developed a rotating bar winding rotor.
