| Abstract(J) | 主機モータの巻線を切り替えて効率を向上する巻線切替システムが提案されている。本稿では、巻線の直並列を切り替える1Y/2Y方式を考案し、機械式、電子式1Y/2Y切替および、先行研究の中性点切替方式の電費を算定した。その結果，電費改善量は機械式1Y/2Y切替が最も優れ、JC08では電子式および中性点切替の4%に対して6%改善した。 Translation |
| Abstract(E) | Winding changeover systems has been proposed to reduce the energy loss by switching the traction motor windings. In this report, we devised a series and parallel switching method(1Y/2Y), and calculated the energy loss of mechanical and electronic 1Y/2Y switching and neutral point switching method of previous study. As a result, mechanical 1Y/2Y switching was the best for the improvement quantity, and the energy loss was reduced by 6% owing to mechanical 1Y/2Y switching compared to 4% of electronic 1Y/2Y and neutral point switching. |
