Thread: Curious Dutch motor; 3-phase 180V??

10 years ago I bought an old Polish Zelenda lathe the the Netherlands.
Buried inside is a Dutch built motor; it's 380V 3-phase, but the plate looks like it was originally 180V.
I've seen pre-war 50hz 120V 3-phase supply in Amsterdam [I was connected to it!], but 180V?

This is just a matter of intellectual curiosity. If the motor was 180, it's been rewound and it works just fine, even with a VFD at double speed.

Look close 480 volt...Phil

I'm looking close, and have looked close, and it sure doesn't look like a 4 to me.
If it was, that would be curious too, as there is and was no European 480V service I know of.

If I invert the colors on that picture and play a bit more I see 3280
So I presume it is standard 380 volts
You can look if KW and Amps fit for a 380 volts Dahlander motor

It took me a few tries, but I see it now.
The 2 looks added later, it's a different type and smaller than the other numbers.
