Abstract: Three Phase Induction motors consumes 60 - 65 of industrial electricity. 1 increase in efficiency of all the motors in india will save the power of 500 MW powers. Lots of research work has been carried out by the researches to control the power consumption in all electrical applications more specifically in high voltage applications. In recent days, it has shown that the mixing of nanofillers to enamel can improve the mechanical, electrical and thermal properties. In this work Al O has been used as nanofillers for coating the winding of 23 induction motor with enamel. The nanofluids are prepared by ball milling method and particle size of the Al2O3 analyzed by Scanning Electron Microscope (SEM). The performance of nanofillers with enamel-coated induction motor is analyzed by the different tests such as open circuit test, short circuit test and load test. It was conformed that the efficiency of the three-phase squirrel cage induction motor coated with enamel filled with Al2O3 nanofillers was increased by 3-4 when compared to that of the three phase squirrel cage induction motor coated with pure enamel fille.
