    Default Servo for lathe spindle

    Hi

    I need some advice about a servo for my lathe spindle

    I own a small lathe that I'm converting to CNC.
    Because the lack of space behind the machine I can't change the 0.8kw motor to a 1.5kw (three phase so I can connect a VFD)
    My idea was to use a AC Servo with VFD. This way I also don't need an encoder for cutting threads.

    But I have no idea what I need to check to make it work.
    Who can give me some advice about this topic.

    I'm looking for something like this. 1.5KW, 3000RPM:

    Most servos can not be driven with a VFD. They usually need a servo driver. There is a difference.
