Abstract(J)xEV駆動用モータにおける位置センサの故障診断や故障時駆動の実現には,モータ停止時の回転子位置(初期磁極位置)を推定する技術が必要である。
本稿では,電圧ベクトルの印加で生じる電流値から磁気飽和特性と突極性のそれぞれに基づいて磁極極性・磁極位置を同時に抽出し,短時間で初期磁極位置を推定する技術を述べる。

Translation

Abstract(E)It is necessary to estimate initial rotor position of electric motor in order to realize the failure diagnosis of rotor position sensor or the operation at the time of the sensor failure in xEV applications. This paper describes an initial rotor position estimation technology in a short time that identifies the magnetic polarity and position at the same time based on the magnetic saturation and the magnetic saliency characteristics using motor current caused by the voltage vector injection.

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.
