Abstract

In the recent days, there was a magnificent improvement in the performance of the electrical machines by coating the windings of the machines by the enamel filled with various nano fillers. Those types of electrical machines were simply called as energy efficient electrical machines or nano electrical machines. This technique was now applicable in DC shunt motors to improve the performance and thermal withstanding capacity of the motor. The maximum efficiency of the DC shunt motor was improved by 4.8% by coating the windings of the motor with the enamel filled with nano SiO2. The maximum temperature of the DC shunt motor was reduced by 10.81% by coating the windings of the motor with the enamel filled with nano SiO2. Hence these shunt motor fed drives were called as Energy efficient DC Shunt motor fed drives. The life time of the motors was also improved by reducing the losses and the maximum temperature rise of the motors. This kind of work can be extended for different types of motors by coating with several nano fillers such as TiO2, ZnO, and ZrO2 and also with the mixture of nano composites for both AC and DC motors.
