Abstract

It has been examined that the addition of nanocomposites to the enamel can greatly improve the thermal, mechanical and electrical properties of enamel. In electrical machines, enamel was used mainly in three different ways: impregnation, coating and adhesion. 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. Heat run test was performed on electrical machines to determine the total loss of energy dissipated as heat. It was a well-known fact that the operating temperature of an electric machine has a very strong relationship with the life duration of the insulation. The insulating enamel mostly used for coating the machine windings were organic in nature, and were adversely affected by thermal decomposition. But the addition of nanocomposites to the enamel has increased the temperature withstanding capacity of the induction motor.
