It has been shown that the addition of nano composites to the enamel can greatly improve the thermal, mechanical and electrical properties of enamel. A nano composite (TiO2+SiO2) has been tested as nano filler. The micro particles of TiO2 and SiO2 are converted into nano particles with the help of ball mill. Scanning electron microscope (SEM) has been used to augment the particle size of nano composite. The nano sio2 and tio2 materials taken in the ratio of 1:3 were mixed with enamel by using ultrasonic vibrator. The enamel filled with nano composite was coated on the windings of a motor. The values of electromagnetic inference produced by normal induction motor and nano coated induction motor was measured and analyzed. There was a reduction of 15 to 60% in the values of the electromagnetic interference produced by the normal induction motor when compared to that of nano composite filled enamel coated induction motor at various distances. Hence, the nano composite filled enamel coated induction motor can be used to reduce the electromagnetic interference produced by the induction motor. This method can be used as one of the method to reduce the electromagnetic interference by the induction motors. This method does not require extra cost and hence, it is also an economical method of reducing electromagnetic interference produced by motors.
