| Summary: | The generation of heat is one of the main problems in the induction motor because it directly affects the performance, efficiency, speed fluctuations, and lifetime of motors. These entities mainly due to improper insulation of the electrical motors and this will avoid by using proper enamel filled nanofiller insulation. In this paper, a novel hybrid TiO2/Al2O3/MoS2based enamel insulation for a 3 phases squirrel cage induction motor was proposed to improve the thermal and electrical properties by using Taguchi and RSM in experimentally. To find an optimal combination of hybrid material TiO2/Al2O3/MoS2, the four different levels of 0.02, 0.04, 0.08 and 0.1 volume percentage with L16 orthogonal array was proposed. Design matrix, ANOVA, S/N ratio, main effect plot, normal probability plot, and surface plot were measured to analyze the optimum combination of the nanofiller to reduce the heat generation problem in an induction motor. ANOVA result shows the TiO2 has a significant effect on the thermal withstanding capacity of the induction motor due to its insulation property compared to Al2O3 and MoS2. A comparison result reveals the hybrid nanocoated induction has better thermal withstanding capacity in the range of 9%–12% compared to normal enamel filled induction motor. This article also analyzes the efficiency and electromagnetic interference of the hybrid nanocoated induction motor.
