Energy efficient single phase induction motor

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”.
