    Default Recommend me a VFD?

    I am hoping someone could give me an ebay link to follow and hit buy.

    I'm going to get either a 1.5kw or 2.2kw motor for my mill (whichever is better for 10 amps 240v)

    or
    3 PH Three Phase Electric Motor 415V 1.5kW 2HP 1400rpm 4 Pole IMB3 IMB5 IMB14 | eBay
    And I'm just wondering would this VFD do the job for both of them?

    I'm going to use it for a CNC conversion on my mill.

    The first question is: do you have 3-phase power?
    The next question is: do you know the difference between star and delta-wound motors?
    From the answers to these two questions, we may be able to make some recommendations.
    You selected links to 415V motors which do not specify if they are delta or star-wound motors, but you put in a link for a 220V VFD. That is either a 'mouse mistake' or you need some 'educating' before making your choices.
    Happy to help with either!
    Cheers, Joe
