Estimation of Losses on 3Φ Nano Coated Induction Motor

Abstract:

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%.
