      最初から界磁添加励磁制御に手を出して痛い目にあったので確実な抵抗制御車で性能曲線のお勉強しようかな...と さて何ができあがるのか...

      抵抗制御は限流値読めたら一瞬(机上の空論)ですので是非 143期待してます!

      なるほど限流値で行き詰まりました。 求め方がわからないのですがどのようにして求められるのでしょうか?ご教授願います。

      あ、143はMT57でしたね。こちらは一時間定格150Aなのでこれが基本となります。 限流値というのは一定ではなくて、欲しいパワー(あとは変電所容量とか)によって変更可能なんですよね。 ですから応荷重制御を搭載していると乗車率によって限流値が200Aとかに上がったりするんすよ。基本は1時間定格かな…

      あとはこんな感じ。 1ノッチでは150Aには進段できずS1をたどるだけ、S2からは色のラインをたどって2ノッチならS9終段、3ならQ7P7...といった感じで進段します。抵抗制御車両が加速の時カッコカッコするのが、進段しているときに加速力が伸びてる実感として感じられる感じっすかね…説明が難しいですpic.twitter.com/Y9jtjjPLGp

          色々調べて進段する~のところは何となくわかったのですが、限流値というのは1時間定格が基本...といった認識で良いんでしょうか。すべては理解できていない感じなので間違っていたら申し訳ないです。
