Is a VFD Good or Bad for Old 3 Phase Motors?

I have been looking at a couple of power tools that have a 220v 3 phase motor. I was wanting to avoid having to install a rotary converter. But I have been told the VFDs that some folks use are bad for older motors and can ruin them. Can you share any insight into this?
Thank you in advance.
