Abstract(J)今後の自動車の電動化に伴い, モータに用いられるNd-Fe-B系磁石の需要は高まる一方で将来的な供給不足が懸念される. この課題を解決するには, 高性能DyフリーNd-Fe-B系異方性ボンド磁石を用いた電動アクスルの高速回転化による省資源化が有効だと考えられる. 本稿では開発した高性能磁石と、それを用いた電動アクスルの展望を述べる.


Abstract(E)With the electrification of automobiles in the future, the demand for Nd-Fe-B magnets used in those motors will increase. On the otherhand, there are concerns about future supply shortages of them. To solve this problem, resource saving of E-Axle by high-speed rotation using high-performance Dy-free Nd-Fe-B anisotropic bonded magnets is effective. This paper describes the development of high-performance magnets and future prospects of E-Axle using them.

About search


How to use the search box

You can enter up to 5 search conditions. The number of search boxes can be increased or decreased with the "+" and "-" buttons on the right.
If you enter multiple words separated by spaces in one search box, the data that "contains all" of the entered words will be searched (AND search).
Example) X (space) Y → "X and Y (including)"

How to use "AND" and "OR" pull-down

If "AND" is specified, the "contains both" data of the phrase entered in the previous and next search boxes will be searched. If you specify "OR", the data that "contains" any of the words entered in the search boxes before and after is searched.
Example) X AND Y → "X and Y (including)"  X OR Z → "X or Z (including)"
If AND and OR searches are mixed, OR search has priority.
Example) X AND Y OR Z → X AND (Y OR Z)
If AND search and multiple OR search are mixed, OR search has priority.
Example) W AND X OR Y OR Z → W AND (X OR Y OR Z)

How to use the search filters

Use the "search filters" when you want to narrow down the search results, such as when there are too many search results. If you check each item, the search results will be narrowed down to only the data that includes that item.
The number in "()" after each item is the number of data that includes that item.
