Abstract

Single phase induction motors are widely used in domestic and industrial appliances. It has been observed that 1% increase in efficiency of all the motors in India will save 500 MW powers which needs the initial generation cost of 2000 crores. The efficiency of a single phase induction motor can be substantially improved by controlling the voltage to frequency ratio (V/Hz). Other methods of improving the efficiency of the single phase induction motor are 1. Coating enameled copper wire filled with several nano fillers such as Al2O3, SiO2, TiO2, CNT, ZrO2 and so on. 2. Coating of induction motor filled with nano fillers. One such method was adopted in this project after a serious literature survey. Based on the previous works, actions were taken to use the enamel filled with Al2O3 nanofiller as the coating for the induction motor to improve its efficiency. Amazingly there was a tremendous improvement in the efficiency of the induction motor by 6% and hence the motor was also called as “Energy Efficient Single Induction Motor”.
