Abstract(J)本稿では、モータ、PCU、ECU、バッテリーなどEV/HEVの主要な電動部品における最新の振動解析・可視化技術に関して述べる。モータ振動は、モータ試験システムと3軸振動加速度センサを用いて計測した。また、空隙磁束は径方向および周方向磁束を検出する探りコイルで構成されたフィルム状の磁気センサを用いて計測した。その結果、周方向磁束の5次、7次高調波成分の減少が振動加速度の6次成分を低下させ、振動抑制に効果があることを示した。

Abstract(E)This paper describes the visualization and analysis techniques of vibration for electrical components such as motors, PCUs, ECUs and batteries, which is key parts determining EV and HEV efficiencies and performances. Motor vibration was analyzed by using a motor evaluation system and triaxial accelerometer. Air gap magnetic flux was measured by the film-like magnetic sensor, which consist of diameter direction and tangent direction search coils. As a result, it has been shown that decrease of 5th and 7th order harmonic tangent direction magnetic flux reduces 6th order vibration acceleration.

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.
