| Outline of Final Research Achievements |
To research on a building factor of motor core loss, an iron loss of ring core in sinusoidal excitation and inverter excitation as well as a motor core loss in sinusoidal excitation and inverter excitation are measured. An electrical steel used in the motor core is usually evaluated by sinusoidal excitation due to the rule of JIS and IEC. However, the electrical motor is usually used in the inverter excitation. Therefore, the core loss increase of motor design and the one of the inverter excitation should be considered to be a different issue. The measured iron loss data show that the core loss increase of inverter excitation is only 4 %, but the one of the motor design is 17 %. So the motor shape research is said to be more important than the inverter excitation research. The guideline for the motor core loss reduction is clearly shown by this research.

| Academic Significance and Societal Importance of the Research Achievements |
これまでのモータコア損計測評価は、実使用条件のインバータ励磁下でのコア損計測を中心に行われていたが、これにより両者の分離が明確になり、モータの研究、設計の指針といえる。モータコア形状だけではなく，インバータ励磁方法に対しても総合的に議論できるようになった．
