Some VFDs will work with some PM motors, but different control algorithms are required. If the drive maker didn't specifically include PM control, it most likely won't work. > That would make the spindle drive much > easier.

If you have AC servo drives already, you _really_ want to search for docs, etc, before you give up and ebay them. AC servos are much more complex than DC servos - if you've got drives that are matched to the motors, use them.
