In this recent decades, there was a significant growth in the applications of nano technology in the field of electrical and electronics engineering. In this research paper, the estimation of the different types of losses on a normal and nano coated three phase induction motor was done and hence the results were compared with each other. From these researches, it found that the mechanical losses were reduced by 33.33% in the motor after nano coating whereas stator iron losses were reduced by 13.8%. Stator losses were reduced up to 16.7% by coating the windings of the motor with the enamel filled with nano fillers of SiO2 and Al2O3 whereas rotor copper losses were high in the nano coated motor. The output mechanical power developed by the normal motor was increased by 39% with the application of the nano fillers to the enamel used for the coatings of the windings of the motor whereas the gross rotor torque was improved by 42%. The power factor of the motor was also improved by nano coating by 15.5%.

Abstract:In this paper, the basic terms and definitions of nano technology was discussed. The characteristics, advantages and disadvantages of nano technology were discussed. Applications of nano technology were also mentioned. This paper would be useful to young engineers to study the fundamentals of nano particles. Two approaches used for nano technology were also elaborated.
