Abstract
This study aims to verify the application of amorphous metals to high-speed drive motors. We propose a new high-speed motor that applies amorphous metal to ultra-high-speed motors used in home appliances. The proposed motor can reduce both the iron loss and copper loss compared to conventional vacuum cleaner motors. We performed characteristic analysis and prototype evaluation through magnetic field analysis of the proposed motor. The analysis results at the same operating point, confirm that the efficiency improvement effect was approximately 1% compared to the highest grade electrorical steel sheet machine. The prototype evaluation results of the new high-speed motor, confirm that various characteristics obtained by the analysis could be reproduced. As a result of evaluating prototypes composed of different materials, the effect of improving motor efficiency by applying amorphous metal is confirmed quantitatively.
