Abstract(J)低速から高速への加速中にモータ巻線を機械的に切り替える機械式巻線切替システムを提案する。提案システムによって,大型トラックで要求されるワイドレンジのNT特性を満足しながら,モータ体格を大きく低減できることを示した。変速機構を追加する必要がないため,駆動システムとしての小型化も可能となる。

Abstract(E)This report presents a mechanical winding-changeover system to reduce motor size and satisfies the wide-range rotation-torque (NT) characteristics required for heavy-duty trucks. We have adopted multi contacts to downsize the winding-changeover device and changed the winding connections: 1Y connection at low-speed and high-torque operation, whereas 2Y connection at high-speed and low-torque operation. FEA results showed that a 220 kW PM motor with the proposed winding-changeover system could satisfy the required NT curve with minimal motor-core-stuck length.

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.
