It has been found that the addition of nanofillers to the enamel can greatly improve the thermal, mechanical and electrical properties of enamel. Al2O3 has been used as nano filler. The micro particles of Al2O3were converted into nano particles with the help of ball mill. Scanning electron microscope (SEM) has been used to augment the particle size of the nano powder. The nano filler was mixed with enamel by using ultrasonic vibrator. The enamel filled with nano filler was coated on the windings of the single phase induction motor. The performance analysis of the single phase induction motor was carried out by no load test, blocked rotor test and load test. Based on the calculations and result obtained by the above tests, the efficiency of the induction motor coated with enamel filled with nano filler of Al2O3was increased by 6% when compared to that of induction motor coated with pure enamel. Heat run test was also performed on this motor to determine the total loss of energy dissipated as heat.
