>what could make such a design better than a traditional inductive motor

Traditional induction motors, compared to these with wound rotors, are heavier and bigger in size for the same power output, and have less efficiency especially at starting/low-speeds.

that is only true if you don't have a VFD. At that point you can basically get whatever you want out of them until they melt or blow out a bearing

So then it comes down to cost? If this is cheaper than a motor and vfd, then it's still a win?

Source: the one time I restored a massive JT Towsley jointer and had to get a vfd for the giant motor I had to put on it. In other words, I have no idea what I'm really talking about.

as others commented, this is not new tech. It's the result of the PR department needing to make a press release.
