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%.
This paper discusses about the survey on the various magazines, conference papers and journals for understanding the properties of enamelled copper wires mixed with nano fillers, fundamental methods for synthesis and characterization of carbon nanotubes. From all these papers, it was noted that the research work carried out in an enamelled copper wires filled with nano fillers has shown better results. It was also recorded that the research work was carried mostly with single metal catalysts and very little amount of research work has been carried out on the synthesis of carbon nanotubes using bimetallic catalysts.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
