Summary: | The main purpose of this study is to improve efficiency of an induction motor. This paper describes a design approach to reduce both fundamental and harmonic losses using magnetic field analysis, wherein small air gap length and magnetic wedges are applied. It is clarified that reducing the air gap length and applying magnetic wedges decreases both fundamental and harmonic losses. The combination of the stray load loss and iron loss of the developed motor decreased by 19% compared with that of the conventional motor, and the total loss of the developed motor reduced by 15%. |
