    Default 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.zelenda-uz4-motor-plate.jpg

    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.
