Abstract(J)自動車を始めとする様々な分野で電動化が進んでおり、電動システム向けモータは、小型・高出力密度化が求められている。そこで、モータの高速化による小型化を図るため、高強度回転子構造を開発した。応力集中を防ぐ磁石配置、磁石挿入孔形状を考案することで、回転子回転速度22000r/minを達成した。加えて、要素試験やモータ駆動試験から電気特性・強度特性が目標値を達成することを確認した。

Translation

Abstract(E)Electrification is progressing in a variety of fields such as automobiles and construction machineries. Motors for electric systems are required to be small and achieve high power density. In this paper, we developed a small motor with rotation speed of 22000r/min by reducing stress concentration. Additionally, we carried out a spin test and motor drive tests. We have achieved target values of electric and strength characteristics.

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.
