    VFD for spindle motor with no HP rating on tag

    I have a Cielle CNC router that I'm retrofitting and need to figure out what VFD I need to run the spindle but the motor tag does not appear to have a HP rating on it. It is Italian though so I don't know; maybe it's there and I'm missing it.

    Motor tag below for reference. Any help?

    Greetings,

    Google is your friend.

    Search "1.7 kw to HP"

    I get 2.3 HP, at the higher rpm.

    Cheers,

    Dave

    2.5Hp rated to be on the safe side!

    746w = 1hp.
