TM-AC鉄鋼ライン向け直流機互換三相誘導モータ
製鉄所のラインを動かすモータを直流から交流に。
製鉄所などのラインを動かすモータには、長年に渡って「直流モータ」が使われてきました。しかし現在の主流は「交流モータ」です。直流モータからそのまま置きかえることで、老朽化したラインを省エネ性能に優れたものに刷新できるのがこの「TM-AC鉄鋼ライン向け直流機互換」。本モータは鉄鋼のライン駆動に特化しています。

TMEIC offers products which have three speed ratings to mutch the existing DC motor ratings. (Full, Half, and Quarter Speed designs)
| Frame Size | Standard Speed | Half Speed | Low Speed(Quarter Speed) | |||
|---|---|---|---|---|---|---|
| Rated Output(kW) | Rotational Speed(min-1) | Rated Output(kW) | Rotational Speed(min-1) | Rated Output(kW) | Rotational Speed(min-1) | |
| 806 | 44 | 1300 | 22 | 650 | 11 | 325 |
| 808 | 74 | 1150 | 37 | 575 | 14.8 | 287 |
| 810 | 104 | 1100 | 52 | 550 | 20.8 | 275 |
| 812 | 150 | 1030 | 75 | 515 | 30 | 216 |
| 814 | 220 | 1000 | 110 | 500 | 44 | 200 |
