Abstract(J)ステータの円環0次振動低減を目的に,ワニスを考慮した解析モデルを構築した.ワニスの剛性をコイルの直交異方性で,含浸率をコイルとステータコアの結合面積でモデル化した結果,含浸率の変更による振動レベルの差分を誤差0.2dBで予測可能にした.また,含浸率が40~60%の時に最大6dBの振動低減を確認した.

Translation

Abstract(E)Analysis model of stator which is considered the influence of varnish is developed to reduce the vibration of stator. The rigidity of varnish is modeled as anisotropy of coil and the varnish impregnation ratio is modeled as connection area between coil and stator core. As a result, the difference in vibration level due to the change in varnish impregnation ratio can be predicted with an error of 0.2dB. The vibration of stator can be reduced up to 6dB when the varnish impregnation ratio is 40% to 60%.

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.
