His ac motor was made in 1888.
Nikola Tesla invented the induction motor with rotating magnetic field that made unit drives for machines feasible and made AC power transmission an economic necessity. With this, Tesla set the basis for machinery and households to be powered with ac electriticity.
Nikola Tesla had his ac motors ready and patented in 1890.
Nikola Tesla was greatly influenced by Vedic philosophy, and thus the realisation that Reality is a Dynamic Unity.
Tesla introduced his motors and electrical systems in a classic paper, "A New System of Alternating Current Motors and Transformers" which he delivered before the American Institute of Electrical Engineers in 1888.
AC Induction Motor
it is like the AC motor that he built
Tesla dropped from college from depression. In his recovery he came out with the idea. When he finally got better, Tesla realized his mind had been working on the AC motor the whole time -- and one day, walking with a friend, he had the answer! "The idea came like a flash of lightning," he said, "and in an instant the truth was revealed." Tesla picked up a twig and began drawing in the dirt. "See my motor," he said to his friend. "Here."

During his lifetime, Tesla invented fluorescent lighting, the Tesla induction motor, the Tesla coil, and developed the alternating current (AC) electrical supply system that included a motor and transformer, and 3-phase electricity.
He invented it in 1888.

Nikola Tesla invented the poly-phase induction motor in 1883.
