In this study technical and economical analysis of energy efficiency application to high efficient motors has been done. For this purpose, first of all, the motors with known power and working time which are used by Tofas Turkish Automobile Factory, the largest car manufacturer in Turkey, have been examined. Research of the high efficient motors that will replace the chosen engines has been done and financial statement on their use has been analyzed. In the first step, 158 selected motors have been examined. It has been determined that high efficient motors of a new generation will amortize themselves in 30 months. 14 motors have been eliminated from this replacement procedure because amortization period would be too long to them. Under these circumferences, amortization period will decrease to 16 months for the rest of new motors.
