It has been observed addition of nano fillers to the enamel can greatly improve the thermal, mechanical and electrical properties of enamel. In this research work SiO2 has been used as nano filler. The micro particles of SiO2 were 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 SiO2 was increased by 5% when compared to that of induction motor coated with pure enamel.
