要約(英語): A high Bs nanocrystal alloy has been used for the teeth portion of the stator core of distributed winding IPM motors to improve their efficiency by expanding the area. In an amorphous metal, the efficiency decreases in the high torque region therefore the aim is to improve the efficiency. Accordingly, analysis studies and prototype evaluations were conducted to quantitatively understand the effect of improving the efficiency. Based on the results of the analysis, the effect of the magnetic properties of the high Bs nanocrystal alloy on the torque characteristics of the motor and the effect on the iron loss is clarified. The results reveal that the prototype motor for verification can improve the efficiency in all operating areas compared to the electrical steel sheet machine.
