Radial Gap Type Motor using Amorphous Metal for Iron Core

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 widely used motors, a motor structure that can apply amorphous metal to a radial gap motor was studied. We propose a structure that uses only amorphous metal for the teeth of a radial gap type motor. It was found that the losses can be reduced by using amorphous metal for the teeth part. By prototyping a motor for industrial use with the proposed structure, a high efficiency of IE5 class was achieved.
