  journal={Proceedings of the IEEE},
This paper briefly reviews the history of the induction motor from its invention by Nicola Tesla in 1888 through the various stages of its development-the invention of the cast aluminum squirrelcage winding, improvements in magnetic steel and insulation, and the progressive reduction of the dimensions for a given horsepower rating, so that today a 100-hp motor has the same mounting dimensions as the 7.5-hp motor of 1897.
