In an AC motor, a "Dahlander circuit" can be used to alter the number of poles in the drive circuit in order to double its speed. It's apparently used in HVAC systems, which is where I've encountered it. [wikipedia.de]
The full translation is probably best rendered as "Dahlander pole-changing circuit" (e.g. here), but in different circumstances I could see either "Dahlander pole changing" or "Dahlander circuit".
