Smart answer:

Your search for Who invented induction motor returned the following results:

Nikola Tesla

In 1887, Nikola Tesla invented an AC induction motor that Tesla successfully patented a year later.

Galileo Ferraris

The first alternating-current commutatorless induction motor was invented by Galileo Ferraris in 1885.

Tesla

In 1887 Tesla created the first induction motor which worked on alternating current, creating a new chapter in power engineering.

Galileo Ferraris and Nikola Tesla

Alternating current, with its ability to transmit power more efficiently over long distances via the use of transformers, developed rapidly in the 1880s and 1890s with transformer designs by Károly Zipernowsky, Ottó Bláthy and Miksa Déri (later called ZBD transformers), Lucien Gaulard, John Dixon Gibbs and William Stanley, Jr.. Practical AC motor designs including induction motors were independently invented by Galileo Ferraris and Nikola Tesla and further developed into a practical three-phase form by Mikhail Dolivo-Dobrovolsky and Charles Eugene Lancelot Brown.

Nikola Tesla and Michail Dolivo-Dobrovolsky

Nikola Tesla and Michail Dolivo-Dobrovolsky invented the first practical induction motors using a rotating magnetic field - previously all commercial motors were DC, with expensive commutators, high-maintenance brushes, and characteristics unsuitable for operation on an alternating current network.

or Galileo Ferraris

The AC induction motor was invented by either Nikola Tesla or Galileo Ferraris, depending on who you ask.

Mr. Tesla

Mr. Tesla was the first inventor of the induction motor and the system of alternating current power transmission, popularly known as two-phase, three-phase, or poly-phase systems, which created a revolution in electrical engineering and are now universally adopted.
