Distributed Winding IPM Motor using Amorphous Metal Teeth

Abstract

We have been studying the application of amorphous metal with low loss to axial gap motors. However, since radial gap motors are the most widly used motors, a motor structure that can apply amorphous metal to a radial gap motor was studied. In our previous study, we reported the study on SPM motors with concentrated winding. In this study, we evaluated the effect of high efficiency on the distributed winding IPM motor with high magnetic flux density inside the iron core. As a result, it was confirmed that the efficiency can be improved by reducing the iron core loss.
