Did Nikola Tesla or Galileo Ferraris invent induction motors

Did Nikola Tesla or Galileo Ferraris invent induction motorsMany sources say the discoveries and inventions of Nikola Tesla and Galileo Ferraris regarding the invention of induction motor were made entirely independently of each other.

When George Westinghouse and his team of engineers were designing their AC power distribution system, Westinghouse saw the invention of induction motor as a critical part of his final design.

Westinghouse saw Tesla's ideas as something he could use in his quest to develop AC, and purchased Tesla's alternating current patents. Not taking any chances as to who did it first, Westinghouse also purchased a U.S. patent option on induction motors from Galileo Ferraris.

Galileo Ferraris (1847-1897) was an Italian physicist and electrical engineer known for introducing the concept of the rotating magnetic field, and the invention of the rotating magnetic field asynchronous motor. Ferraris was involved in early experiments in AC power distance transmission which occurred in Germany and Italy in the early 1880s.

Galileo Ferraris is little known in the United States, having spent his entire life in Italy, and never worked with industrial giants like Edison and Westinghouse.

Nikola Tesla (1856-1943) was a Serbian born inventor who grew up in an area of the Austro-Hungarian Empire that is the modern-day country of Croatia. In 1884 Tesla moved to United States to work for Thomas Edison. In 1888 Tesla presented to the American Institute of Electrical Engineers his polyphase alternating current system in the report “A New System of Alternating Current Motors and Transformers.”

Tesla is more well known in the United States, having spent most of his adult life in the US. Having worked for Edison and Westinghouse, Tesla has become a cult hero.

Who did it first?

Some sources name Galileo Ferraris as the inventor of induction motors based on his research of the rotary magnetic field started in 1885. In March 1888, Ferraris published his research in a paper to the Royal Academy of Sciences in Turin, Italy.

Some sources name Nikola Tesla as the inventor of induction motors based on his filling of US patent 381968, granted on May 1, 1888.

By virtue of the many Nikola Tesla fans that frequent various Cult of Tesla websites, they may say that Nikola Tesla should be considered more important than Galileo Ferraris, even though the claim to the invention of induction motor should be a shared honor.
